Jean paid $53.20 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 4 hours = $7.00
Amount that Jean paid after the fourth hour
= 53.20 - 7.00
= $46.20
Number of sets of $3.30
= 46.20 ÷ 3.30
= 14
Duration of the additional time
= 14 x
12 = 7 h
Greatest number of hours that Jean parked her car at the carpark
= 4 + 7
= 11 h
Answer(s): 11 h
