Olivia paid $13.40 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Olivia paid for the first 2 hours = $5.00
Amount that Olivia paid after the second hour
= 13.40 - 5.00
= $8.40
Number of sets of $2.10
= 8.40 ÷ 2.10
= 4
Duration of the additional time
= 4 x
12 = 2 h
Greatest number of hours that Olivia parked her car at the carpark
= 2 + 2
= 4 h
Answer(s): 4 h
