Fiona paid $31.60 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 = $6.00
Amount that Fiona paid after the second hour
= 31.60 - 6.00
= $25.60
Number of sets of $3.20
= 25.60 ÷ 3.20
= 8
Duration of the additional time
= 8 x
12 = 4 h
Greatest number of hours that Fiona parked her car at the carpark
= 2 + 4
= 6 h
Answer(s): 6 h
