Roshel paid $14.20 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Roshel paid for the first 4 hours = $4.00
Amount that Roshel paid after the fourth hour
= 14.20 - 4.00
= $10.20
Number of sets of $3.40
= 10.20 ÷ 3.40
= 3
Duration of the additional time
= 3 x
12 = 1.5 h
Greatest number of hours that Roshel parked her car at the carpark
= 4 + 1.5
= 5.5 h
Answer(s): 5.5 h
