Parking in a student lot costs $3 for the first half hour and $1.25 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 $8
***
let t=hours after first half hour
1.25t+3≤8
1.25t≤5
t≤5/1.25
t≤4
longest time that a student can park in this lot for $8=4+1/2 hours
