Raeann paid $16.50 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Raeann paid for the first 4 hours = $8.00
Amount that Raeann paid after the fourth hour
= 16.50 - 8.00
= $8.50
Number of sets of $1.70
= 8.50 ÷ 1.70
= 5
Duration of the additional time
= 5 x
12 = 2.5 h
Greatest number of hours that Raeann parked her car at the carpark
= 4 + 2.5
= 6.5 h
Answer(s): 6.5 h
