Zara paid $22.30 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Zara paid for the first 2 hours = $8.00
Amount that Zara paid after the second hour
= 22.30 - 8.00
= $14.30
Number of sets of $1.10
= 14.30 ÷ 1.10
= 13
Duration of the additional time
= 13 x
12 = 6.5 h
Greatest number of hours that Zara parked her car at the carpark
= 2 + 6.5
= 8.5 h
Answer(s): 8.5 h
