The table shows the parking rates at a carpark.
Duration |
Charges |
First 2 hours |
$3.00 |
After the second hour |
$3.40 per 12 hour or part thereof |
Eva paid $30.20 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Eva paid for the first 2 hours = $3.00
Amount that Eva paid after the second hour
= 30.20 - 3.00
= $27.20
Number of sets of $3.40
= 27.20 ÷ 3.40
= 8
Duration of the additional time
= 8 x
12 = 4 h
Greatest number of hours that Eva parked her car at the carpark
= 2 + 4
= 6 h
Answer(s): 6 h
