Cindy paid $34.60 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 4 hours = $9.00
Amount that Cindy paid after the fourth hour
= 34.60 - 9.00
= $25.60
Number of sets of $1.60
= 25.60 ÷ 1.60
= 16
Duration of the additional time
= 16 x
12 = 8 h
Greatest number of hours that Cindy parked her car at the carpark
= 4 + 8
= 12 h
Answer(s): 12 h
