PSLE The table shows the charges for laser gun rental. Peter rented a laser gun from 11.22 a.m. to 3.48 p.m.. How much did he pay?
Laser Gun rental |
Charges |
First hour |
$3 |
Additional 12 hour or part thereof |
$1.80 |
From 11.22 a.m. to 12.22 p.m. = 1 h
From 12.22 p.m. to 3.48 p.m. = 3 h 26 min = 206 min
Sets of additional
12 hour
= 206 ÷ 30
= 6 r 26
Total number of sets of additional
12 hour and part thereof to pay for
= 6 + 1
= 7
Amount to pay from 11.22 a.m. to 12.22 a.m. = $3
Amount to pay from 12.22 a.m. to 3.48 p.m. = 7 x 1.80 = $12.60
Total amount that Peter paid
= 3 + 12.60
= $15.60
Answer(s): $15.60
