PSLE The table shows the charges for skateboard rental. Peter rented a skateboard from 11.50 a.m. to 4.10 p.m.. How much did he pay?
Skateboard rental |
Charges |
First hour |
$5 |
Additional 12 hour or part thereof |
$1.40 |
From 11.50 a.m. to 12.50 p.m. = 1 h
From 12.50 p.m. to 4.10 p.m. = 3 h 20 min = 200 min
Sets of additional
12 hour
= 200 ÷ 30
= 6 r 20
Total number of sets of additional
12 hour and part thereof to pay for
= 6 + 1
= 7
Amount to pay from 11.50 a.m. to 12.50 a.m. = $5
Amount to pay from 12.50 a.m. to 4.10 p.m. = 7 x 1.40 = $9.80
Total amount that Peter paid
= 5 + 9.80
= $14.80
Answer(s): $14.80
