After the fourth hour |
$2.70 per 12 hour or part thereof |
Victoria paid $26.90 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Victoria paid for the first 4 hours = $8.00
Amount that Victoria paid after the fourth hour
= 26.90 - 8.00
= $18.90
Number of sets of $2.70
= 18.90 ÷ 2.70
= 7
Duration of the additional time
= 7 x
12 = 3.5 h
Greatest number of hours that Victoria parked her car at the carpark
= 4 + 3.5
= 7.5 h
Answer(s): 7.5 h
