Which function can be used to determine how much money he has left over after x rides? (1 point) Of(x) = 1.25x + 64 f(x) = -16x + $80 f(x) = -1.25x + 64 f(x) = -1.25x - 64 2 (03.05) mall hthable below that is the correct testament​

Answer 1

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

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
