$3.10 per 12 hour or part thereof |
Ivory paid $48.40 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 2 hours = $5.00
Amount that Ivory paid after the second hour
= 48.40 - 5.00
= $43.40
Number of sets of $3.10
= 43.40 ÷ 3.10
= 14
Duration of the additional time
= 14 x
12 = 7 h
Greatest number of hours that Ivory parked her car at the carpark
= 2 + 7
= 9 h
Answer(s): 9 h
