Ivory paid $34.10 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Ivory paid for the first 2 hours = $8.00
Amount that Ivory paid after the second hour
= 34.10 - 8.00
= $26.10
Number of sets of $2.90
= 26.10 ÷ 2.90
= 9
Duration of the additional time
= 9 x
12 = 4.5 h
Greatest number of hours that Ivory parked her car at the carpark
= 2 + 4.5
= 6.5 h
Answer(s): 6.5 h
