The table shows the parking rates at a carpark.
Duration |
Charges |
First 3 hours |
$3.00 |
After the third hour |
$1.40 per 12 hour or part thereof |
Hazel paid $11.40 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Hazel paid for the first 3 hours = $3.00
Amount that Hazel paid after the third hour
= 11.40 - 3.00
= $8.40
Number of sets of $1.40
= 8.40 ÷ 1.40
= 6
Duration of the additional time
= 6 x
12 = 3 h
Greatest number of hours that Hazel parked her car at the carpark
= 3 + 3
= 6 h
Answer(s): 6 h
