First 2 hours |
$5.00 |
After the second hour |
$2.30 per 12 hour or part thereof |
Yen paid $32.60 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Yen paid for the first 2 hours = $5.00
Amount that Yen paid after the second hour
= 32.60 - 5.00
= $27.60
Number of sets of $2.30
= 27.60 ÷ 2.30
= 12
Duration of the additional time
= 12 x
12 = 6 h
Greatest number of hours that Yen parked her car at the carpark
= 2 + 6
= 8 h
Answer(s): 8 h
