Question

The revenue from selling x tickets is r(x) = 10x. The cost for buying x tickets is c(x) = 8x + 40. The profit from selling x tickets is p(x) = r(x) – c(x).9. What is p(x)? *

Answer 1

p(X) = r(X) - c(X).9

⇔ p(X) = 10x - (8x+ 40).9

⇔ p(X) = 10x - 72x - 360

⇔ p(X) = -62x - 360

Explanation:

Answer 2

p(x)=2x-40

Explanation:

Substitute the variables

p(x)=10x-(8x+40)

p(x)= 10x-8x-40

p(x)=2x-40
