PSLE The table shows the charges for laser gun rental. Ivan rented a laser gun from 11.49 a.m. to 4.17 p.m.. How much did he pay?
Laser Gun rental |
Charges |
First hour |
$5 |
Additional 12 hour or part thereof |
$1.60 |
From 11.49 a.m. to 12.49 p.m. = 1 h
From 12.49 p.m. to 4.17 p.m. = 3 h 28 min = 208 min
Sets of additional
12 hour
= 208 ÷ 30
= 6 r 28
Total number of sets of additional
12 hour and part thereof to pay for
= 6 + 1
= 7
Amount to pay from 11.49 a.m. to 12.49 a.m. = $5
Amount to pay from 12.49 a.m. to 4.17 p.m. = 7 x 1.60 = $11.20
Total amount that Ivan paid
= 5 + 11.20
= $16.20
Answer(s): $16.20
