PSLE The table shows the charges for laser gun rental. Pierre rented a laser gun from 11.20 a.m. to 2.12 p.m.. How much did he pay?
Laser Gun rental |
Charges |
First hour |
$4 |
Additional 12 hour or part thereof |
$1.30 |
From 11.20 a.m. to 12.20 p.m. = 1 h
From 12.20 p.m. to 2.12 p.m. = 1 h 52 min = 112 min
Sets of additional
12 hour
= 112 ÷ 30
= 3 r 22
Total number of sets of additional
12 hour and part thereof to pay for
= 3 + 1
= 4
Amount to pay from 11.20 a.m. to 12.20 a.m. = $4
Amount to pay from 12.20 a.m. to 2.12 p.m. = 4 x 1.30 = $5.20
Total amount that Pierre paid
= 4 + 5.20
= $9.20
Answer(s): $9.20
