PSLE The table shows the charges for laser gun rental. Wesley rented a laser gun from 11.38 a.m. to 3.41 p.m.. How much did he pay?
Laser Gun rental |
Charges |
First hour |
$2 |
Additional 12 hour or part thereof |
$1.90 |
From 11.38 a.m. to 12.38 p.m. = 1 h
From 12.38 p.m. to 3.41 p.m. = 3 h 3 min = 183 min
Sets of additional
12 hour
= 183 ÷ 30
= 6 r 3
Total number of sets of additional
12 hour and part thereof to pay for
= 6 + 1
= 7
Amount to pay from 11.38 a.m. to 12.38 a.m. = $2
Amount to pay from 12.38 a.m. to 3.41 p.m. = 7 x 1.90 = $13.30
Total amount that Wesley paid
= 2 + 13.30
= $15.30
Answer(s): $15.30
