After the fourth hour |
$1.20 per 12 hour or part thereof |
Jade paid $22.60 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Jade paid for the first 4 hours = $7.00
Amount that Jade paid after the fourth hour
= 22.60 - 7.00
= $15.60
Number of sets of $1.20
= 15.60 ÷ 1.20
= 13
Duration of the additional time
= 13 x
12 = 6.5 h
Greatest number of hours that Jade parked her car at the carpark
= 4 + 6.5
= 10.5 h
Answer(s): 10.5 h
