PSLE The table shows the charges for skateboard rental. Ryan rented a skateboard from 11.45 a.m. to 3.36 p.m.. How much did he pay?
Skateboard rental |
Charges |
First hour |
$4 |
Additional 12 hour or part thereof |
$1.20 |
From 11.45 a.m. to 12.45 p.m. = 1 h
From 12.45 p.m. to 3.36 p.m. = 2 h 51 min = 171 min
Sets of additional
12 hour
= 171 ÷ 30
= 5 r 21
Total number of sets of additional
12 hour and part thereof to pay for
= 5 + 1
= 6
Amount to pay from 11.45 a.m. to 12.45 a.m. = $4
Amount to pay from 12.45 a.m. to 3.36 p.m. = 6 x 1.20 = $7.20
Total amount that Ryan paid
= 4 + 7.20
= $11.20
Answer(s): $11.20
