Fiona paid $21.40 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Fiona paid for the first 2 hours = $7.00
Amount that Fiona paid after the second hour
= 21.40 - 7.00
= $14.40
Number of sets of $1.60
= 14.40 ÷ 1.60
= 9
Duration of the additional time
= 9 x
12 = 4.5 h
Greatest number of hours that Fiona parked her car at the carpark
= 2 + 4.5
= 6.5 h
Answer(s): 6.5 h
