After the second hour |
$2.60 per 12 hour or part thereof |
Olivia paid $16.40 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Olivia paid for the first 2 hours = $6.00
Amount that Olivia paid after the second hour
= 16.40 - 6.00
= $10.40
Number of sets of $2.60
= 10.40 ÷ 2.60
= 4
Duration of the additional time
= 4 x
12 = 2 h
Greatest number of hours that Olivia parked her car at the carpark
= 2 + 2
= 4 h
Answer(s): 4 h
