Cindy paid $46.50 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Cindy paid for the first 2 hours = $6.00
Amount that Cindy paid after the second hour
= 46.50 - 6.00
= $40.50
Number of sets of $2.70
= 40.50 ÷ 2.70
= 15
Duration of the additional time
= 15 x
12 = 7.5 h
Greatest number of hours that Cindy parked her car at the carpark
= 2 + 7.5
= 9.5 h
Answer(s): 9.5 h
