PSLE The table shows the charges for laser gun rental. Flynn rented a laser gun from 11.18 a.m. to 4.35 p.m.. How much did he pay?
Laser Gun rental |
Charges |
First hour |
$3 |
Additional 12 hour or part thereof |
$1.60 |
From 11.18 a.m. to 12.18 p.m. = 1 h
From 12.18 p.m. to 4.35 p.m. = 4 h 17 min = 257 min
Sets of additional
12 hour
= 257 ÷ 30
= 8 r 17
Total number of sets of additional
12 hour and part thereof to pay for
= 8 + 1
= 9
Amount to pay from 11.18 a.m. to 12.18 a.m. = $3
Amount to pay from 12.18 a.m. to 4.35 p.m. = 9 x 1.60 = $14.40
Total amount that Flynn paid
= 3 + 14.40
= $17.40
Answer(s): $17.40
