PSLE The table shows the charges for laser gun rental. Howard rented a laser gun from 11.32 a.m. to 3.38 p.m.. How much did he pay?
Laser Gun rental |
Charges |
First hour |
$3 |
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 3.38 p.m. = 3 h 6 min = 186 min
Sets of additional
12 hour
= 186 ÷ 30
= 6 r 6
Total number of sets of additional
12 hour and part thereof to pay for
= 6 + 1
= 7
Amount to pay from 11.32 a.m. to 12.32 a.m. = $3
Amount to pay from 12.32 a.m. to 3.38 p.m. = 7 x 1.20 = $8.40
Total amount that Howard paid
= 3 + 8.40
= $11.40
Answer(s): $11.40
