After the second hour |
$1.40 per 12 hour or part thereof |
Olivia paid $14.60 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 = $9.00
Amount that Olivia paid after the second hour
= 14.60 - 9.00
= $5.60
Number of sets of $1.40
= 5.60 ÷ 1.40
= 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
