After the fourth hour |
$1.60 per 12 hour or part thereof |
Ivory paid $29.20 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Ivory paid for the first 4 hours = $10.00
Amount that Ivory paid after the fourth hour
= 29.20 - 10.00
= $19.20
Number of sets of $1.60
= 19.20 ÷ 1.60
= 12
Duration of the additional time
= 12 x
12 = 6 h
Greatest number of hours that Ivory parked her car at the carpark
= 4 + 6
= 10 h
Answer(s): 10 h
