PSLE The table shows the charges for skateboard rental. David rented a skateboard from 11.16 a.m. to 4.26 p.m.. How much did he pay?
Skateboard rental |
Charges |
First hour |
$5 |
Additional 12 hour or part thereof |
$1.50 |
From 11.16 a.m. to 12.16 p.m. = 1 h
From 12.16 p.m. to 4.26 p.m. = 4 h 10 min = 250 min
Sets of additional
12 hour
= 250 ÷ 30
= 8 r 10
Total number of sets of additional
12 hour and part thereof to pay for
= 8 + 1
= 9
Amount to pay from 11.16 a.m. to 12.16 a.m. = $5
Amount to pay from 12.16 a.m. to 4.26 p.m. = 9 x 1.50 = $13.50
Total amount that David paid
= 5 + 13.50
= $18.50
Answer(s): $18.50
