PSLE The table shows the charges for laser gun rental. Bobby rented a laser gun from 11.24 a.m. to 2.43 p.m.. How much did he pay?
Laser Gun rental |
Charges |
First hour |
$2 |
Additional 12 hour or part thereof |
$1.10 |
From 11.24 a.m. to 12.24 p.m. = 1 h
From 12.24 p.m. to 2.43 p.m. = 2 h 19 min = 139 min
Sets of additional
12 hour
= 139 ÷ 30
= 4 r 19
Total number of sets of additional
12 hour and part thereof to pay for
= 4 + 1
= 5
Amount to pay from 11.24 a.m. to 12.24 a.m. = $2
Amount to pay from 12.24 a.m. to 2.43 p.m. = 5 x 1.10 = $5.50
Total amount that Bobby paid
= 2 + 5.50
= $7.50
Answer(s): $7.50
