Computer rental |
Charges |
First hour |
$4 |
Additional 12 hour or part thereof |
$1.10 |
From 11.39 a.m. to 12.39 p.m. = 1 h
From 12.39 p.m. to 2.30 p.m. = 1 h 51 min = 111 min
Sets of additional
12 hour
= 111 ÷ 30
= 3 r 21
Total number of sets of additional
12 hour and part thereof to pay for
= 3 + 1
= 4
Amount to pay from 11.39 a.m. to 12.39 a.m. = $4
Amount to pay from 12.39 a.m. to 2.30 p.m. = 4 x 1.10 = $4.40
Total amount that Brandon paid
= 4 + 4.40
= $8.40
Answer(s): $8.40
