Tiffany paid $24.40 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Tiffany paid for the first 3 hours = $10.00
Amount that Tiffany paid after the third hour
= 24.40 - 10.00
= $14.40
Number of sets of $2.40
= 14.40 ÷ 2.40
= 6
Duration of the additional time
= 6 x
12 = 3 h
Greatest number of hours that Tiffany parked her car at the carpark
= 3 + 3
= 6 h
Answer(s): 6 h
