Nicole paid $27.50 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Nicole paid for the first 3 hours = $8.00
Amount that Nicole paid after the third hour
= 27.50 - 8.00
= $19.50
Number of sets of $1.50
= 19.50 ÷ 1.50
= 13
Duration of the additional time
= 13 x
12 = 6.5 h
Greatest number of hours that Nicole parked her car at the carpark
= 3 + 6.5
= 9.5 h
Answer(s): 9.5 h
