A bookstore costs $75 a day to keep open, and spends $10 for each book it
sells. The store charges $15 for each book it sells. If n represents the number
of books sold, which equation represents the cost function for this
bookstore?
O A. C = 15n+75
O B. C= 10n + 75
O C. C= 75n+ 10
O D. C= 750 + 15

Answer 1

Step-by-step explanation:

The answer should be B

Answer 2

The cost function of this bookstore is 10n + 75

What is cost function?

A cost function is a formula used to predict the cost that will be experienced at a certain activity level.

According to the given problem,

Cost to open bookstore for a day - $75

Price for selling each book = 10

Considering number of books to be n,

Total cost for selling each book = $(10×n)

Therefore total cost price =  $( 10n + 75)

Hence, we can conclude that the total cost function of this bookstore is represented by equation 10n + 75
