Winnie paid $11.80 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Winnie paid for the first 3 hours = $8.00
Amount that Winnie paid after the third hour
= 11.80 - 8.00
= $3.80
Number of sets of $1.90
= 3.80 ÷ 1.90
= 2
Duration of the additional time
= 2 x
12 = 1 h
Greatest number of hours that Winnie parked her car at the carpark
= 3 + 1
= 4 h
Answer(s): 4 h
