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 lost for $7?

Answer 1

Well start off by subtracting!

So 7-2 = 5 dollars.

So first half hour and we have 5 dollars left. Next: 5-1.75-1.75 = 1.5

So we got charged for two more hours and have nothing left to pay for either a partial or full hour.

So we add it up .5h+1h+1h = 2.5H longest time to park.

Answer 2

thanks, now i get it
