Elyse paid $11.40 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Elyse paid for the first 2 hours = $9.00
Amount that Elyse paid after the second hour
= 11.40 - 9.00
= $2.40
Number of sets of $1.20
= 2.40 ÷ 1.20
= 2
Duration of the additional time
= 2 x
12 = 1 h
Greatest number of hours that Elyse parked her car at the carpark
= 2 + 1
= 3 h
Answer(s): 3 h
