Parking charges at superior parking garage or five dollars for the first hour and $1.50 for each additional 30 minutes if Margo has $12.50 what is the maximum amount of the time she will be able to park her car in the garage

Answer 1

30 min = 0.5 h

$1.50 for each additional 30 minutes means:

$1.5 / 30 min = $1.5 / 0.5 h = $3 / h

for each additional hours

x = the number of hours the car was parked more then 1h

The price of parking = $5 + x • $3

She has $12.50 so:

5 + 3 x = 12.5

Subtract 5 to bith sides

3 x = 7.5

x = 7.5 / 3

x = 2.5

She will be able to park her car in the garage first hour plus 2.5 hours.

She will be able to park her car in the garage for a maximum of 3.5 hours.
