$9.00 |
After the second hour |
$2.20 per 12 hour or part thereof |
Nicole paid $26.60 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
= 26.60 - 9.00
= $17.60
Number of sets of $2.20
= 17.60 ÷ 2.20
= 8
Duration of the additional time
= 8 x
12 = 4 h
Greatest number of hours that Nicole parked her car at the carpark
= 2 + 4
= 6 h
Answer(s): 6 h
