A product is sold at a price of $120 per unit and its variable cost is $80 per unit. The fixed expenses of the business are $8,000 per year. Find (i) BEP in $ and units, (ii) profits made when sales are 240 units. Calculate the profit and do a CVP Analysis.
Answers
(i) BEP in $: $8,000
BEP in units: 100 units
(ii) Profits made when sales are 240 units: $4,800
(i) BEP in $ and units:
To find the Break-Even Point (BEP) in dollars, we need to divide the fixed expenses by the contribution margin per unit. The contribution margin per unit is the selling price minus the variable cost per unit.
BEP in $ = Fixed expenses / Contribution margin per unit
BEP in $ = $8,000 / ($120 - $80) = $8,000 / $40 = $8,000
The BEP in dollars is $8,000.
To find the BEP in units, we divide the fixed expenses by the contribution margin ratio.
BEP in units = Fixed expenses / Contribution margin ratio
Contribution margin ratio = Contribution margin per unit / Selling price per unit
Contribution margin ratio = ($120 - $80) / $120 = $40 / $120 = 1/3
BEP in units = $8,000 / (1/3) = $8,000 * 3 = 300 units
The BEP in units is 300 units.
(ii) Profits made when sales are 240 units:
To calculate the profit, we need to subtract the total costs (fixed costs + variable costs) from the total sales.
Variable costs = Variable cost per unit * Number of units sold
Variable costs = $80 * 240 = $19,200
Total costs = Fixed expenses + Variable costs
Total costs = $8,000 + $19,200 = $27,200
Profit = Total sales - Total costs
Profit = (Selling price per unit * Number of units sold) - Total costs
Profit = ($120 * 240) - $27,200
Profit = $28,800 - $27,200
Profit = $1,600
The profit made when sales are 240 units is $1,600.
CVP Analysis:
Cost-Volume-Profit (CVP) analysis is a tool used to analyze the relationship between costs, volume, and profits. It helps in understanding how changes in sales volume affect profitability.
In this case, the CVP analysis can be performed using the given data:
Sales revenue = Selling price per unit * Number of units sold
Sales revenue = $120 * 240 = $28,800
Variable costs = Variable cost per unit * Number of units sold
Variable costs = $80 * 240 = $19,200
Contribution margin = Sales revenue - Variable costs
Contribution margin = $28,800 - $19,200 = $9,600
Contribution margin ratio = Contribution margin / Sales revenue
Contribution margin ratio = $9,600 / $28,800 ≈ 0.3333
Break-Even Point (BEP) in units = Fixed expenses / Contribution margin per unit
BEP in units = $8,000 / $40 = 200 units
Profit = (Selling price per unit * Number of units sold) - Total costs
Profit = ($120 * 240) - ($8,000 + $19,200)
Profit = $28,800 - $27,200
Profit = $1,600
By conducting a CVP analysis, we can determine the Break-Even Point, contribution margin, and analyze the profitability based on the given data.

______ states that individuals do not differ in whether or not they have a specific gene, but rather in the form that it takes.
Answers
The concept that individuals do not differ in whether or not they have a specific gene, but rather in the form that it takes, is known as the polymorphism.
Polymorphism refers to the coexistence of multiple versions of a given gene or DNA sequence in a population. These different versions, or alleles, can vary in their nucleotide sequence and may affect the function or expression of the encoded protein. Polymorphism is an important concept in genetics and evolutionary biology, as it can contribute to the diversity of traits and phenotypes observed within and between populations, and can influence the adaptation and evolution of species over time.

Kaya had an organ transplant. She went to the doctor a week later, and the doctor did a blood test. Her lymphocyte count
had increased. She went to the doctor a month later for the same test, and her lymphocyte count was higher. What is the
best explanation as to why her lymphocyte levels were increasing?
O Kaya was given antibiotics to prevent infections.
Kaya's antigens were attacking the tissue.
Kaya was not tissue typed prior to her surgery, and her body is mounting an immune response.
O Kaya took her immunosuppressant drugs weekly, which increased her lymphocyte count.
Answers
Answer:
The best explanation for the increased lymphocyte levels in Kaya is that she was not tissue typed prior to her surgery, and her body is mounting an immune response.
Explanation:
When performing an organ transplant, it must be verified whether the organ to be transplanted is compatible -by tissue typing- with the recipient, since it is recognized as a foreign body by the body and can be rejected.
One of the immunological responses to organ rejection is called cell rejection, involving T-helper and cytotoxic lymphocytes.
It is very likely that in Kaya's case the tests have not been performed correctly, and she is experiencing rejection of the organ she received. The progressive increase in lymphocytes may be an indication of this.
The other options are not possible because:
Administering antibiotics should not raise lymphocyte levels. There is no evidence of antigen attack. Immunosuppressant drugs do not increase lymphocyte count.Please put the following in order from Least Inclusive to MOST inclusive...

One way to link a tidal energy power plant working model with different habitats is to study the impact of the power plant on each habitat. For example, in a desert habitat, the power plant may have a minimal impact on the ecosystem, while in a forest habitat, the power plant may have a greater impact on the plants and animals living there. Similarly, in a polar region, the power plant may have an impact on the ice and the animals living there, while in an aquatic habitat, the power plant may have an impact on the water quality and marine life. Additionally, you could research how the different habitats can be used to generate tidal energy.

why are annual rings of mature woody dicot stem composed of light and dark sub-rings
Answers
Annual rings in mature woody dicot stems are composed of light and dark sub-rings due to the different rates of growth during the spring and summer seasons.
The annual rings in woody dicot stems are formed by the activity of the vascular cambium, which is a layer of cells that divides and produces new cells towards the inside and outside of the stem. During the spring, when there is plenty of water and nutrients available, the cambium produces larger and thinner-walled cells, resulting in the light-colored sub-ring.
In the summer, when water and nutrient availability decreases, the cambium produces smaller and thicker-walled cells, resulting in the darker sub-ring. This variation in growth rates is due to changes in environmental conditions, and the resulting pattern of light and dark sub-rings can be used to determine the age and growth history of a tree or woody plant.

what happens during an autoimmune disease such as multiple sclerosis? group of answer choices a primary immune response is triggered. immune system cells attack health body cells. memory cells are no longer produced. infectious agents are able to hide in immune system cells. immune cells are no longer able to make antibodies.
Answers
During an autoimmune disease like multiple sclerosis, the immune system cells mistakenly attack healthy cells in the body.
Autoimmune diseases occur when the immune system, which is designed to protect the body from harmful substances and infections, mistakenly identifies the body's own cells as foreign and launches an immune response against them. In the case of multiple sclerosis (MS), immune system cells, particularly T cells, cross the blood-brain barrier and attack the myelin sheath, a protective covering of nerve fibers in the central nervous system. This immune-mediated attack leads to inflammation, damage, and disruption of the nerve signals, resulting in various neurological symptoms such as muscle weakness, impaired coordination, sensory disturbances, and cognitive impairments.
In MS, the immune system's attack on the myelin sheath can lead to the formation of scar tissue (sclerosis) in affected areas of the brain and spinal cord. This disrupts the normal transmission of nerve impulses, causing the symptoms experienced by individuals with MS. It is important to note that the exact cause of autoimmune diseases like MS is not fully understood, and factors such as genetic predisposition, environmental triggers, and dysregulation of the immune system play a role in their development.
