Computer rental |
Charges |
First hour |
$4 |
Additional 12 hour or part thereof |
$1.50 |
From 11.24 a.m. to 12.24 p.m. = 1 h
From 12.24 p.m. to 3.42 p.m. = 3 h 18 min = 198 min
Sets of additional
12 hour
= 198 ÷ 30
= 6 r 18
Total number of sets of additional
12 hour and part thereof to pay for
= 6 + 1
= 7
Amount to pay from 11.24 a.m. to 12.24 a.m. = $4
Amount to pay from 12.24 a.m. to 3.42 p.m. = 7 x 1.50 = $10.50
Total amount that Simon paid
= 4 + 10.50
= $14.50
Answer(s): $14.50
