PSLE The table shows the charges for laser gun rental. Simon rented a laser gun from 11.26 a.m. to 4.38 p.m.. How much did he pay?
Laser Gun rental |
Charges |
First hour |
$2 |
Additional 12 hour or part thereof |
$1.10 |
From 11.26 a.m. to 12.26 p.m. = 1 h
From 12.26 p.m. to 4.38 p.m. = 4 h 12 min = 252 min
Sets of additional
12 hour
= 252 ÷ 30
= 8 r 12
Total number of sets of additional
12 hour and part thereof to pay for
= 8 + 1
= 9
Amount to pay from 11.26 a.m. to 12.26 a.m. = $2
Amount to pay from 12.26 a.m. to 4.38 p.m. = 9 x 1.10 = $9.90
Total amount that Simon paid
= 2 + 9.90
= $11.90
Answer(s): $11.90
