The revenue from selling x bracelets is r(x) = 8x.
The cost of buying x bracelets is c(x) = 3x + 12.
The profit from selling x bracelets is p(x) = f(x) - c(x).
Write a function for p(x), the profit from selling x bracelets.
O A. p(x) = 11x - 12
O B. p(x) = 11x + 12
O C. p(x) = 5x - 12
O D. p(x) = 5x + 12

Answer 1

C. p(x) = 5x - 12.

Explanation:

p(x) = 8x - (3x + 12) (Note you have to put the 3x+12 in parentheses).

p(x) = 8x - 3x - 12

p(x) = 5x - 12
