Hilda paid $9.40 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Hilda paid for the first 3 hours = $5.00
Amount that Hilda paid after the third hour
= 9.40 - 5.00
= $4.40
Number of sets of $1.10
= 4.40 ÷ 1.10
= 4
Duration of the additional time
= 4 x
12 = 2 h
Greatest number of hours that Hilda parked her car at the carpark
= 3 + 2
= 5 h
Answer(s): 5 h
