Charges |
First 3 hours |
$9.00 |
After the third hour |
$1.30 per 12 hour or part thereof |
Pamela paid $19.40 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Pamela paid for the first 3 hours = $9.00
Amount that Pamela paid after the third hour
= 19.40 - 9.00
= $10.40
Number of sets of $1.30
= 10.40 ÷ 1.30
= 8
Duration of the additional time
= 8 x
12 = 4 h
Greatest number of hours that Pamela parked her car at the carpark
= 3 + 4
= 7 h
Answer(s): 7 h
