Question

At a carnival, you pay $15 for admission, plus $3 for each ride that you go on.

a. write a function A(r) that models the amount "A", in dollars, that you would spend to ride "r" rides at a carnival.

b. find the inverse of A(r). show work.

c. what does the equation inverse of the function found in part b represent in the context of the problem? explain your answer. ​

Answer 1

A. a(r)=3r+15

B. r ( A ) = 31 A − 5A = 3r + 15 A − 15 = 3rA − 15 = r 3r = 31 A − 5

C. This function represents the number of rides r you could go on if you plan to spend A dollars at the carnival.
