PSLE The table shows the charges for laser gun rental. Wesley rented a laser gun from 11.24 a.m. to 2.11 p.m.. How much did he pay?
Laser Gun rental |
Charges |
First hour |
$2 |
Additional 12 hour or part thereof |
$1.40 |
From 11.24 a.m. to 12.24 p.m. = 1 h
From 12.24 p.m. to 2.11 p.m. = 1 h 47 min = 107 min
Sets of additional
12 hour
= 107 ÷ 30
= 3 r 17
Total number of sets of additional
12 hour and part thereof to pay for
= 3 + 1
= 4
Amount to pay from 11.24 a.m. to 12.24 a.m. = $2
Amount to pay from 12.24 a.m. to 2.11 p.m. = 4 x 1.40 = $5.60
Total amount that Wesley paid
= 2 + 5.60
= $7.60
Answer(s): $7.60
