PSLE The table shows the charges for laser gun rental. Ian rented a laser gun from 11.43 a.m. to 2.11 p.m.. How much did he pay?
Laser Gun rental |
Charges |
First hour |
$3 |
Additional 12 hour or part thereof |
$1.10 |
From 11.43 a.m. to 12.43 p.m. = 1 h
From 12.43 p.m. to 2.11 p.m. = 1 h 28 min = 88 min
Sets of additional
12 hour
= 88 ÷ 30
= 2 r 28
Total number of sets of additional
12 hour and part thereof to pay for
= 2 + 1
= 3
Amount to pay from 11.43 a.m. to 12.43 a.m. = $3
Amount to pay from 12.43 a.m. to 2.11 p.m. = 3 x 1.10 = $3.30
Total amount that Ian paid
= 3 + 3.30
= $6.30
Answer(s): $6.30
