After the fourth hour |
$1.60 per 12 hour or part thereof |
Esther paid $14.60 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Esther paid for the first 4 hours = $5.00
Amount that Esther paid after the fourth hour
= 14.60 - 5.00
= $9.60
Number of sets of $1.60
= 9.60 ÷ 1.60
= 6
Duration of the additional time
= 6 x
12 = 3 h
Greatest number of hours that Esther parked her car at the carpark
= 4 + 3
= 7 h
Answer(s): 7 h
