Computer rental |
Charges |
First hour |
$3 |
Additional 12 hour or part thereof |
$1.10 |
From 11.47 a.m. to 12.47 p.m. = 1 h
From 12.47 p.m. to 2.44 p.m. = 1 h 57 min = 117 min
Sets of additional
12 hour
= 117 ÷ 30
= 3 r 27
Total number of sets of additional
12 hour and part thereof to pay for
= 3 + 1
= 4
Amount to pay from 11.47 a.m. to 12.47 a.m. = $3
Amount to pay from 12.47 a.m. to 2.44 p.m. = 4 x 1.10 = $4.40
Total amount that Neave paid
= 3 + 4.40
= $7.40
Answer(s): $7.40
