$7.00 |
After the second hour |
$1.10 per 12 hour or part thereof |
Opal paid $11.40 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Opal paid for the first 2 hours = $7.00
Amount that Opal paid after the second hour
= 11.40 - 7.00
= $4.40
Number of sets of $1.10
= 4.40 ÷ 1.10
= 4
Duration of the additional time
= 4 x
12 = 2 h
Greatest number of hours that Opal parked her car at the carpark
= 2 + 2
= 4 h
Answer(s): 4 h
