Computer rental |
Charges |
First hour |
$2 |
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 3.36 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 11.16 a.m. to 12.16 a.m. = $2
Amount to pay from 12.16 a.m. to 3.36 p.m. = 7 x 1.50 = $10.50
Total amount that Eric paid
= 2 + 10.50
= $12.50
Answer(s): $12.50
