I'm giving away 50 points to whoever correctly answers and fully explains this for me!!! Your friend has $80 when he goes to the fair. He spends $4 to enter the fair and $12 on food. Rides at the fair cost $1.25 per ride.

The function f(x) = -1.25x + 64 can be used to determine how much money he has left over after x rides? What does f(17) represent?

A. Your friend paid for 17 rides and spent $42.75.

B. Your friend paid for 17 rides and had $37.25 left over.

C. Your friend paid for 17 rides and had $42.75 left over.

D. Your friend paid for 17 rides and spent $37.25.
