Fanny paid $14.40 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Fanny paid for the first 2 hours = $9.00
Amount that Fanny paid after the second hour
= 14.40 - 9.00
= $5.40
Number of sets of $1.80
= 5.40 ÷ 1.80
= 3
Duration of the additional time
= 3 x
12 = 1.5 h
Greatest number of hours that Fanny parked her car at the carpark
= 2 + 1.5
= 3.5 h
Answer(s): 3.5 h
