The table shows the parking rates at a carpark.
Duration |
Charges |
First 4 hours |
$7.00 |
After the fourth hour |
$2.20 per 12 hour or part thereof |
Victoria paid $20.20 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Victoria paid for the first 4 hours = $7.00
Amount that Victoria paid after the fourth hour
= 20.20 - 7.00
= $13.20
Number of sets of $2.20
= 13.20 ÷ 2.20
= 6
Duration of the additional time
= 6 x
12 = 3 h
Greatest number of hours that Victoria parked her car at the carpark
= 4 + 3
= 7 h
Answer(s): 7 h
