Question

A parking garage charges $5 for the first hour, $10 for up to two hours, and $12 for the entire day. Let G be the dollar cost of parking for t hours. How much would it be for 1/2 an hour and how much would it be for 1 3/4hour

Answer 1

For the first two hours, the charges per hour is $10/2 = $ 5 per hour

for 1/2 an hour, the cost will be 1/2 x 5 = $2.5

for 1 3/4 hour, the cost will be 1 3/4 x $5 = 7/4 x $5 = $8.75
