The revenue from selling x hats is r(x) = 18x.
The cost of buying x hats is c(x) = 8x+ 30.
The profit from selling x hats is p(x) = r(x) - c(x).


Write a function for p(x), the profit from selling x hats.

A. p(x) = 10x - 30
B. p(x) = 26x + 30
C. p(x) = 26x - 30
D. p(x) = 10x + 30

Respuesta :

Answer:

  • A. p(x) = 10x - 30

Step-by-step explanation:

Given:

  • r(x) = 18x and
  • c(x) = 8x+ 30

Find p(x) by substituting the above into the following equation:

  • p(x) = r(x) - c(x)
  • p(x) = 18x - (8x + 30) = 18x - 8x - 30 = 10x - 30

Correct choice is A
