Tammy paid $45.80 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Tammy paid for the first 2 hours = $5.00
Amount that Tammy paid after the second hour
= 45.80 - 5.00
= $40.80
Number of sets of $3.40
= 40.80 ÷ 3.40
= 12
Duration of the additional time
= 12 x
12 = 6 h
Greatest number of hours that Tammy parked her car at the carpark
= 2 + 6
= 8 h
Answer(s): 8 h
