$6.00 |
After the second hour |
$1.90 per 12 hour or part thereof |
Pamela paid $9.80 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Pamela paid for the first 2 hours = $6.00
Amount that Pamela paid after the second hour
= 9.80 - 6.00
= $3.80
Number of sets of $1.90
= 3.80 ÷ 1.90
= 2
Duration of the additional time
= 2 x
12 = 1 h
Greatest number of hours that Pamela parked her car at the carpark
= 2 + 1
= 3 h
Answer(s): 3 h
