PSLE The table shows the charges for laser gun rental. Brandon rented a laser gun from 11.43 a.m. to 4.35 p.m.. How much did he pay?
Laser Gun rental |
Charges |
First hour |
$4 |
Additional 12 hour or part thereof |
$1.40 |
From 11.43 a.m. to 12.43 p.m. = 1 h
From 12.43 p.m. to 4.35 p.m. = 3 h 52 min = 232 min
Sets of additional
12 hour
= 232 ÷ 30
= 7 r 22
Total number of sets of additional
12 hour and part thereof to pay for
= 7 + 1
= 8
Amount to pay from 11.43 a.m. to 12.43 a.m. = $4
Amount to pay from 12.43 a.m. to 4.35 p.m. = 8 x 1.40 = $11.20
Total amount that Brandon paid
= 4 + 11.20
= $15.20
Answer(s): $15.20
