After the second hour |
$2.40 per 12 hour or part thereof |
Gem paid $24.60 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Gem paid for the first 2 hours = $3.00
Amount that Gem paid after the second hour
= 24.60 - 3.00
= $21.60
Number of sets of $2.40
= 21.60 ÷ 2.40
= 9
Duration of the additional time
= 9 x
12 = 4.5 h
Greatest number of hours that Gem parked her car at the carpark
= 2 + 4.5
= 6.5 h
Answer(s): 6.5 h
