PSLE The table shows the charges for skateboard rental. Ahmad rented a skateboard from 11.33 a.m. to 3.50 p.m.. How much did he pay?
Skateboard rental |
Charges |
First hour |
$3 |
Additional 12 hour or part thereof |
$1.80 |
From 11.33 a.m. to 12.33 p.m. = 1 h
From 12.33 p.m. to 3.50 p.m. = 3 h 17 min = 197 min
Sets of additional
12 hour
= 197 ÷ 30
= 6 r 17
Total number of sets of additional
12 hour and part thereof to pay for
= 6 + 1
= 7
Amount to pay from 11.33 a.m. to 12.33 a.m. = $3
Amount to pay from 12.33 a.m. to 3.50 p.m. = 7 x 1.80 = $12.60
Total amount that Ahmad paid
= 3 + 12.60
= $15.60
Answer(s): $15.60
