Computer rental |
Charges |
First hour |
$5 |
Additional 12 hour or part thereof |
$1.40 |
From 11.35 a.m. to 12.35 p.m. = 1 h
From 12.35 p.m. to 2.15 p.m. = 1 h 40 min = 100 min
Sets of additional
12 hour
= 100 ÷ 30
= 3 r 10
Total number of sets of additional
12 hour and part thereof to pay for
= 3 + 1
= 4
Amount to pay from 11.35 a.m. to 12.35 a.m. = $5
Amount to pay from 12.35 a.m. to 2.15 p.m. = 4 x 1.40 = $5.60
Total amount that Fabian paid
= 5 + 5.60
= $10.60
Answer(s): $10.60
