Question

Parking in a student lot costs $2 for the first half hour and $1.75 for each hour thereafter. A partial hour is charged the same as a full hour. What is the longest time that a student can park in this lot for $9?

Answer 1

5

Answer 2

its 1+(9-2)/1.75=1+4=5

Answer 3

First 30 mins cost $2
X is the time after 30 mins
We have equation: 2+1.75x=9
1.75x=7
x=4
-------> $9 can part: 4hours and 30 mins
