Anna paid $44.40 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Anna paid for the first 3 hours = $8.00
Amount that Anna paid after the third hour
= 44.40 - 8.00
= $36.40
Number of sets of $2.60
= 36.40 ÷ 2.60
= 14
Duration of the additional time
= 14 x
12 = 7 h
Greatest number of hours that Anna parked her car at the carpark
= 3 + 7
= 10 h
Answer(s): 10 h
