After the second hour |
$1.70 per 12 hour or part thereof |
Lynn paid $16.90 for her parking charges. What was the greatest number of hours she parked her car at the carpark?
Amount that Lynn paid for the first 2 hours = $5.00
Amount that Lynn paid after the second hour
= 16.90 - 5.00
= $11.90
Number of sets of $1.70
= 11.90 ÷ 1.70
= 7
Duration of the additional time
= 7 x
12 = 3.5 h
Greatest number of hours that Lynn parked her car at the carpark
= 2 + 3.5
= 5.5 h
Answer(s): 5.5 h
