After the fourth hour |
$2.40 per 12 hour or part thereof |
Tina paid $36.80 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Tina paid for the first 4 hours = $8.00
Amount that Tina paid after the fourth hour
= 36.80 - 8.00
= $28.80
Number of sets of $2.40
= 28.80 ÷ 2.40
= 12
Duration of the additional time
= 12 x
12 = 6 h
Greatest number of hours that Tina parked her car at the carpark
= 4 + 6
= 10 h
Answer(s): 10 h
