Jane paid $43.60 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
= 43.60 - 10.00
= $33.60
Number of sets of $2.40
= 33.60 ÷ 2.40
= 14
Duration of the additional time
= 14 x
12 = 7 h
Greatest number of hours that Jane parked her car at the carpark
= 3 + 7
= 10 h
Answer(s): 10 h
