Answer:
9
Step-by-step explanation:
Given data
Ride ticket= $2
Admission= $7
Amount= $25
We want to find the greatest number of rides
let the number of rides be x
The expression to describe how she spends the amount is given as
y=7+2x
for y= 25, let us find x
25= 7+2x
25-7= 2x
18=3x
x= 18/2
x= 9
Hence the number of rides is 9
