Question

The revenue from selling x tickets to a concert is the represented by the function r(x)=10x. The cost for buying tickets is represented by the function c(x) = 8x+40. The profit made from selling the tickets is represented by the function p(x) = r(x) - c(x). What is p(100)? *

Answer 1

Explanation:

All these fancy terms is confusing. We just need to substitute the original equations into the final problem statement.

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

We can then substitute 100 for x and solve.

`p(100) = 10(100) - 8(100) - 40`
