First 3 hours |
$6.00 |
After the third hour |
$2.90 per 12 hour or part thereof |
Hazel paid $11.80 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Hazel paid for the first 3 hours = $6.00
Amount that Hazel paid after the third hour
= 11.80 - 6.00
= $5.80
Number of sets of $2.90
= 5.80 ÷ 2.90
= 2
Duration of the additional time
= 2 x
12 = 1 h
Greatest number of hours that Hazel parked her car at the carpark
= 3 + 1
= 4 h
Answer(s): 4 h
