Charges |
First 4 hours |
$8.00 |
After the fourth hour |
$1.90 per 12 hour or part thereof |
Sabrina paid $23.20 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Sabrina paid for the first 4 hours = $8.00
Amount that Sabrina paid after the fourth hour
= 23.20 - 8.00
= $15.20
Number of sets of $1.90
= 15.20 ÷ 1.90
= 8
Duration of the additional time
= 8 x
12 = 4 h
Greatest number of hours that Sabrina parked her car at the carpark
= 4 + 4
= 8 h
Answer(s): 8 h
