Natalie paid $12.50 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Natalie paid for the first 2 hours = $5.00
Amount that Natalie paid after the second hour
= 12.50 - 5.00
= $7.50
Number of sets of $2.50
= 7.50 ÷ 2.50
= 3
Duration of the additional time
= 3 x
12 = 1.5 h
Greatest number of hours that Natalie parked her car at the carpark
= 2 + 1.5
= 3.5 h
Answer(s): 3.5 h
