PSLE The table shows the charges for laser gun rental. Billy rented a laser gun from 11.12 a.m. to 2.26 p.m.. How much did he pay?
Laser Gun rental |
Charges |
First hour |
$3 |
Additional 12 hour or part thereof |
$1.50 |
From 11.12 a.m. to 12.12 p.m. = 1 h
From 12.12 p.m. to 2.26 p.m. = 2 h 14 min = 134 min
Sets of additional
12 hour
= 134 ÷ 30
= 4 r 14
Total number of sets of additional
12 hour and part thereof to pay for
= 4 + 1
= 5
Amount to pay from 11.12 a.m. to 12.12 a.m. = $3
Amount to pay from 12.12 a.m. to 2.26 p.m. = 5 x 1.50 = $7.50
Total amount that Billy paid
= 3 + 7.50
= $10.50
Answer(s): $10.50
