Computer rental |
Charges |
First hour |
$2 |
Additional 12 hour or part thereof |
$1.30 |
From 11.12 a.m. to 12.12 p.m. = 1 h
From 12.12 p.m. to 3.44 p.m. = 3 h 32 min = 212 min
Sets of additional
12 hour
= 212 ÷ 30
= 7 r 2
Total number of sets of additional
12 hour and part thereof to pay for
= 7 + 1
= 8
Amount to pay from 11.12 a.m. to 12.12 a.m. = $2
Amount to pay from 12.12 a.m. to 3.44 p.m. = 8 x 1.30 = $10.40
Total amount that Lee paid
= 2 + 10.40
= $12.40
Answer(s): $12.40
