Computer rental |
Charges |
First hour |
$3 |
Additional 12 hour or part thereof |
$1.80 |
From 11.46 a.m. to 12.46 p.m. = 1 h
From 12.46 p.m. to 2.45 p.m. = 1 h 59 min = 119 min
Sets of additional
12 hour
= 119 ÷ 30
= 3 r 29
Total number of sets of additional
12 hour and part thereof to pay for
= 3 + 1
= 4
Amount to pay from 11.46 a.m. to 12.46 a.m. = $3
Amount to pay from 12.46 a.m. to 2.45 p.m. = 4 x 1.80 = $7.20
Total amount that Ken paid
= 3 + 7.20
= $10.20
Answer(s): $10.20
