Computer rental |
Charges |
First hour |
$3 |
Additional 12 hour or part thereof |
$1.60 |
From 11.38 a.m. to 12.38 p.m. = 1 h
From 12.38 p.m. to 4.23 p.m. = 3 h 45 min = 225 min
Sets of additional
12 hour
= 225 ÷ 30
= 7 r 15
Total number of sets of additional
12 hour and part thereof to pay for
= 7 + 1
= 8
Amount to pay from 11.38 a.m. to 12.38 a.m. = $3
Amount to pay from 12.38 a.m. to 4.23 p.m. = 8 x 1.60 = $12.80
Total amount that Will paid
= 3 + 12.80
= $15.80
Answer(s): $15.80
