After the third hour |
$2.60 per 12 hour or part thereof |
Jane paid $25.60 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Jane paid for the first 3 hours = $10.00
Amount that Jane paid after the third hour
= 25.60 - 10.00
= $15.60
Number of sets of $2.60
= 15.60 ÷ 2.60
= 6
Duration of the additional time
= 6 x
12 = 3 h
Greatest number of hours that Jane parked her car at the carpark
= 3 + 3
= 6 h
Answer(s): 6 h
