Computer rental |
Charges |
First hour |
$2 |
Additional 12 hour or part thereof |
$1.30 |
From 11.20 a.m. to 12.20 p.m. = 1 h
From 12.20 p.m. to 3.17 p.m. = 2 h 57 min = 177 min
Sets of additional
12 hour
= 177 ÷ 30
= 5 r 27
Total number of sets of additional
12 hour and part thereof to pay for
= 5 + 1
= 6
Amount to pay from 11.20 a.m. to 12.20 a.m. = $2
Amount to pay from 12.20 a.m. to 3.17 p.m. = 6 x 1.30 = $7.80
Total amount that Michael paid
= 2 + 7.80
= $9.80
Answer(s): $9.80
