Question

Olivia is going to an amusement park. The price of admission into the park is $40, and once she is inside the park, she will have to pay $4 for every ride she rides on. How much money would Olivia have to pay in total if she goes on 13 rides? How much would she have to pay if she goes on r rides?

Cost for 13 rides:
Cost for r rides:

Answer 1

Answer : Total cost : $92

Answer 2

Cost for 13 rides: $92

Cost for r rides: I am guessing it would be 40+4r

Explanation:

If you automatically pay 40 dollars to get in, then that is the constant, and paying 4 dollars per ride is a coefficient, so that would be multiplied by how many rides you go on, the variable. Once you plug those into the equation above, you would get 92 dollars for the thirteen rides.
