After the second hour |
$1.60 per 12 hour or part thereof |
Shiyun paid $15.80 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Shiyun paid for the first 2 hours = $3.00
Amount that Shiyun paid after the second hour
= 15.80 - 3.00
= $12.80
Number of sets of $1.60
= 12.80 ÷ 1.60
= 8
Duration of the additional time
= 8 x
12 = 4 h
Greatest number of hours that Shiyun parked her car at the carpark
= 2 + 4
= 6 h
Answer(s): 6 h
