Select ALL the correct answers.

Maya and her friends are planning a car wash event. Maya creates a function C (x) to model the group's costs for washing x cars and a function R (x) to model the revenue the group will make from washing x cars. The net profit the group will earn is represented by the function P (x) = - 60 + 4.5x, which is equal to R (x) - C (x).

Select the two functions that could represent the cost and revenue for the car wash.

A. R (x) = 10x

B. R (x) = 7x

C. C (x) = 11.5x - 60

D. C (x) = 4.5x + 60

E. R (x) = 8x

F. C (x) = 3.5x + 60
