Natalie paid $35.60 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 4 hours = $8.00
Amount that Natalie paid after the fourth hour
= 35.60 - 8.00
= $27.60
Number of sets of $2.30
= 27.60 ÷ 2.30
= 12
Duration of the additional time
= 12 x
12 = 6 h
Greatest number of hours that Natalie parked her car at the carpark
= 4 + 6
= 10 h
Answer(s): 10 h
