PSLE The table shows the charges for skateboard rental. Glen rented a skateboard from 11.32 a.m. to 4.21 p.m.. How much did he pay?
Skateboard rental |
Charges |
First hour |
$4 |
Additional 12 hour or part thereof |
$1.70 |
From 11.32 a.m. to 12.32 p.m. = 1 h
From 12.32 p.m. to 4.21 p.m. = 3 h 49 min = 229 min
Sets of additional
12 hour
= 229 ÷ 30
= 7 r 19
Total number of sets of additional
12 hour and part thereof to pay for
= 7 + 1
= 8
Amount to pay from 11.32 a.m. to 12.32 a.m. = $4
Amount to pay from 12.32 a.m. to 4.21 p.m. = 8 x 1.70 = $13.60
Total amount that Glen paid
= 4 + 13.60
= $17.60
Answer(s): $17.60
