Jean paid $33.60 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Jean paid for the first 3 hours = $7.00
Amount that Jean paid after the third hour
= 33.60 - 7.00
= $26.60
Number of sets of $1.90
= 26.60 ÷ 1.90
= 14
Duration of the additional time
= 14 x
12 = 7 h
Greatest number of hours that Jean parked her car at the carpark
= 3 + 7
= 10 h
Answer(s): 10 h
