Kimberly paid $40.10 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Kimberly paid for the first 2 hours = $6.00
Amount that Kimberly paid after the second hour
= 40.10 - 6.00
= $34.10
Number of sets of $3.10
= 34.10 ÷ 3.10
= 11
Duration of the additional time
= 11 x
12 = 5.5 h
Greatest number of hours that Kimberly parked her car at the carpark
= 2 + 5.5
= 7.5 h
Answer(s): 7.5 h
