Answer 1

f(x) = -1.25x + 64

Step-by-step explanation:

Answer 2

f(x) = -1.25x + 64 I hope this helps :)

Step-by-step explanation:

total amount of money: $80

He spent $16 for the entrance of the fair and food.

80-(4+12) = 64

After that you subtract $1.25 per ride = -1.25x

Then it gives the function:

f(x) = -1.25x + 64
