$2.10 per 12 hour or part thereof |
Nicole paid $19.50 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 2 hours = $9.00
Amount that Nicole paid after the second hour
= 19.50 - 9.00
= $10.50
Number of sets of $2.10
= 10.50 ÷ 2.10
= 5
Duration of the additional time
= 5 x
12 = 2.5 h
Greatest number of hours that Nicole parked her car at the carpark
= 2 + 2.5
= 4.5 h
Answer(s): 4.5 h
