Elyse paid $8.40 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 3 hours = $3.00
Amount that Elyse paid after the third hour
= 8.40 - 3.00
= $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 Elyse parked her car at the carpark
= 3 + 1.5
= 4.5 h
Answer(s): 4.5 h
