PSLE The table shows the charges for laser gun rental. Reggie rented a laser gun from 11.22 a.m. to 5.41 p.m.. How much did he pay?
Laser Gun rental |
Charges |
First hour |
$4 |
Additional 12 hour or part thereof |
$1.10 |
From 11.22 a.m. to 12.22 p.m. = 1 h
From 12.22 p.m. to 5.41 p.m. = 5 h 19 min = 319 min
Sets of additional
12 hour
= 319 ÷ 30
= 10 r 19
Total number of sets of additional
12 hour and part thereof to pay for
= 10 + 1
= 11
Amount to pay from 11.22 a.m. to 12.22 a.m. = $4
Amount to pay from 12.22 a.m. to 5.41 p.m. = 11 x 1.10 = $12.10
Total amount that Reggie paid
= 4 + 12.10
= $16.10
Answer(s): $16.10
