PSLE The table shows the charges for laser gun rental. Neave rented a laser gun from 11.32 a.m. to 2.21 p.m.. How much did he pay?
Laser Gun rental |
Charges |
First hour |
$5 |
Additional 12 hour or part thereof |
$1.20 |
From 11.32 a.m. to 12.32 p.m. = 1 h
From 12.32 p.m. to 2.21 p.m. = 1 h 49 min = 109 min
Sets of additional
12 hour
= 109 ÷ 30
= 3 r 19
Total number of sets of additional
12 hour and part thereof to pay for
= 3 + 1
= 4
Amount to pay from 11.32 a.m. to 12.32 a.m. = $5
Amount to pay from 12.32 a.m. to 2.21 p.m. = 4 x 1.20 = $4.80
Total amount that Neave paid
= 5 + 4.80
= $9.80
Answer(s): $9.80
