Question

The revenue from selling x shirts is r(x) = 12x.

The cost of buying x shirts is c(x) = 5x + 20.

The profit from selling x shirts is p(x) = r(x) – c(x).

What is p(x)?

A. p(x) = 7x – 20
B. p(x) = 17x + 20
C. p(x) = 17x – 20
D. p(x) = 7x + 20

Answer 1

p(X)=7x-20

Explanation:

correct answer

Answer 2

The answer will be A.
p(x)=r(x) - c(x) Formula
p(x)=(12x) - (5x + 20) Substitution
p(x)=12x - 5x - 20 Distribution of the negative
p(x)=7x - 20 Combine like terms
That is your answer
