Kylie paid $12.60 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Kylie paid for the first 4 hours = $6.00
Amount that Kylie paid after the fourth hour
= 12.60 - 6.00
= $6.60
Number of sets of $3.30
= 6.60 ÷ 3.30
= 2
Duration of the additional time
= 2 x
12 = 1 h
Greatest number of hours that Kylie parked her car at the carpark
= 4 + 1
= 5 h
Answer(s): 5 h
