Round your answers to two decimal places as needed.

You decide to begin selling frozen bananas at the local park. Your cost for each frozen banana is $2.25 plus you have to pay a fixed weekly fee of $120 for the booth. Your plan is to sell each frozen banana for $3.51.

1. Write a function, Cin), to represent your total costs for the week if you sell n frozen bananas. C(n) 2.25 + 120

2. Write a function, R(n), to represent the revenue from the sale of n frozen bananas during the week. R(n) 3,5ln

3. Write a function, P(n), that represents the profits for selling n frozen bananas in a given week. P(n) 1.26n – 120

1. How many frozen bananas must you sell in order to make a positive profit? Write your answer as a whole number. 95.23809524 frozen bananas

2. Complete the following sentence to explain the meaning of #1:

In order to make a profit, I have to sell a minimum of________

## Answers ( )

Answer:1. C(n) = 2.25n + 120

2. R(n) = 3.51n

3. P(n) = 1.26n – 120

1. 96 frozen bananas must be sold in order to make a positive profit.

2. In order to make a profit, I have to sell a minimum of

.96 frozen bananasStep-by-step explanation:1. Write a function, C(n), to represent your total costs for the week if you sell n frozen bananas.Total cost is the addition of total variable cost and total fixed cost. Therefore, the function is as follows:

C(n) = 2.25n + 120

Where

2.25nis the total variable cost while120is the total fixed cost.2. Write a function, R(n), to represent the revenue from the sale of n frozen bananas during the week.Revenue is equal to selling price per unit multiplied by the number of units sold. Therefore, the function is as follows:

R(n) = 3.51 * n

R(n) = 3.51n

Where

3.51is the selling price per unit whilenthe number of units sold.3. Write a function, P(n), that represents the profits for selling n frozen bananas in a given week.Profit is equal to total revenue minus total cost. Therefore, the function can be derived as follows:

P(n) = R(n) – C(n)

P(n) = 3.51n – 2.25n + 120

P(n) = 1.26n – 120

1. How many frozen bananas must you sell in order to make a positive profit? Write your answer as a whole number.This can be obtained by equating the profit function to zero and solve for n as follows:

P(n) = 0 => 1.26n – 120 = 0

Therefore, we have:

1.26n = 120

n = 120 / 1.26

n = 95.2380952380952 frozen bananas

Writing it as a whole number, we have:

n = 95 frozen bananas

However, using this whole number will result in a negative profit by substituting it into the profit function as follows:

P(n) = (1.26 * 95) – 120 = -$0.30

Therefore, n has to be increased by one to 96 which is also a whole number to have a positive profit as follows:

P(n) = (1.26 * 96) – 120 = $0.96

Therefore, 96 frozen bananas must be sold in order to make a positive profit.

2. Complete the following sentence to explain the meaning of #1:In order to make a profit, I have to sell a minimum of
