$9.00 |
After the fourth hour |
$2.50 per 12 hour or part thereof |
Jane paid $16.50 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Jane paid for the first 4 hours = $9.00
Amount that Jane paid after the fourth hour
= 16.50 - 9.00
= $7.50
Number of sets of $2.50
= 7.50 ÷ 2.50
= 3
Duration of the additional time
= 3 x
12 = 1.5 h
Greatest number of hours that Jane parked her car at the carpark
= 4 + 1.5
= 5.5 h
Answer(s): 5.5 h
