$3.10 per 12 hour or part thereof |
Fanny paid $24.60 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Fanny paid for the first 3 hours = $6.00
Amount that Fanny paid after the third hour
= 24.60 - 6.00
= $18.60
Number of sets of $3.10
= 18.60 ÷ 3.10
= 6
Duration of the additional time
= 6 x
12 = 3 h
Greatest number of hours that Fanny parked her car at the carpark
= 3 + 3
= 6 h
Answer(s): 6 h
