PSLE The table shows the charges for laser gun rental. Albert rented a laser gun from 11.32 a.m. to 5.43 p.m.. How much did he pay?
Laser Gun rental |
Charges |
First hour |
$3 |
Additional 12 hour or part thereof |
$1.70 |
From 11.32 a.m. to 12.32 p.m. = 1 h
From 12.32 p.m. to 5.43 p.m. = 5 h 11 min = 311 min
Sets of additional
12 hour
= 311 ÷ 30
= 10 r 11
Total number of sets of additional
12 hour and part thereof to pay for
= 10 + 1
= 11
Amount to pay from 11.32 a.m. to 12.32 a.m. = $3
Amount to pay from 12.32 a.m. to 5.43 p.m. = 11 x 1.70 = $18.70
Total amount that Albert paid
= 3 + 18.70
= $21.70
Answer(s): $21.70
