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. Which function can be used to determine how much money he has left over after x rides? i got f(x) = 1.25x + 64, am i right?

OpenStudy (littlebird):

Wouldn't it be 64-1.25 since he's losing money?

OpenStudy (littlebird):
