PSLE The table shows the charges for laser gun rental. Ryan rented a laser gun from 11.24 a.m. to 4.10 p.m.. How much did he pay?
Laser Gun rental |
Charges |
First hour |
$5 |
Additional 12 hour or part thereof |
$1.20 |
From 11.24 a.m. to 12.24 p.m. = 1 h
From 12.24 p.m. to 4.10 p.m. = 3 h 46 min = 226 min
Sets of additional
12 hour
= 226 ÷ 30
= 7 r 16
Total number of sets of additional
12 hour and part thereof to pay for
= 7 + 1
= 8
Amount to pay from 11.24 a.m. to 12.24 a.m. = $5
Amount to pay from 12.24 a.m. to 4.10 p.m. = 8 x 1.20 = $9.60
Total amount that Ryan paid
= 5 + 9.60
= $14.60
Answer(s): $14.60
