Kylie paid $22.30 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Kylie paid for the first 2 hours = $9.00
Amount that Kylie paid after the second hour
= 22.30 - 9.00
= $13.30
Number of sets of $1.90
= 13.30 ÷ 1.90
= 7
Duration of the additional time
= 7 x
12 = 3.5 h
Greatest number of hours that Kylie parked her car at the carpark
= 2 + 3.5
= 5.5 h
Answer(s): 5.5 h
