Computer rental |
Charges |
First hour |
$3 |
Additional 12 hour or part thereof |
$1.10 |
From 11.46 a.m. to 12.46 p.m. = 1 h
From 12.46 p.m. to 3.34 p.m. = 2 h 48 min = 168 min
Sets of additional
12 hour
= 168 ÷ 30
= 5 r 18
Total number of sets of additional
12 hour and part thereof to pay for
= 5 + 1
= 6
Amount to pay from 11.46 a.m. to 12.46 a.m. = $3
Amount to pay from 12.46 a.m. to 3.34 p.m. = 6 x 1.10 = $6.60
Total amount that Michael paid
= 3 + 6.60
= $9.60
Answer(s): $9.60
