Answer:

f(x) = -1.25(x) + 64

Step-by-step explanation:

Total = $80

Remove $4 + $12 = [$16] for food and entry which leaves us with $64.

For every ride, your friend would spend $1.25 which means that for every ride, you will subtract $1.25 from 64.

f(x) = 64 - 1.25(x) which is also f(x) = -1.25(x) + 64
