Computer rental |
Charges |
First hour |
$4 |
Additional 12 hour or part thereof |
$1.60 |
From 11.12 a.m. to 12.12 p.m. = 1 h
From 12.12 p.m. to 3.43 p.m. = 3 h 31 min = 211 min
Sets of additional
12 hour
= 211 ÷ 30
= 7 r 1
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. = $4
Amount to pay from 12.12 a.m. to 3.43 p.m. = 8 x 1.60 = $12.80
Total amount that Xavier paid
= 4 + 12.80
= $16.80
Answer(s): $16.80
