Xandra paid $24.80 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Xandra paid for the first 2 hours = $8.00
Amount that Xandra paid after the second hour
= 24.80 - 8.00
= $16.80
Number of sets of $2.80
= 16.80 ÷ 2.80
= 6
Duration of the additional time
= 6 x
12 = 3 h
Greatest number of hours that Xandra parked her car at the carpark
= 2 + 3
= 5 h
Answer(s): 5 h
