After the fourth hour |
$1.90 per 12 hour or part thereof |
Penelope paid $14.60 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Penelope paid for the first 4 hours = $7.00
Amount that Penelope paid after the fourth hour
= 14.60 - 7.00
= $7.60
Number of sets of $1.90
= 7.60 ÷ 1.90
= 4
Duration of the additional time
= 4 x
12 = 2 h
Greatest number of hours that Penelope parked her car at the carpark
= 4 + 2
= 6 h
Answer(s): 6 h
