Computer rental |
Charges |
First hour |
$3 |
Additional 12 hour or part thereof |
$1.90 |
From 11.32 a.m. to 12.32 p.m. = 1 h
From 12.32 p.m. to 3.39 p.m. = 3 h 7 min = 187 min
Sets of additional
12 hour
= 187 ÷ 30
= 6 r 7
Total number of sets of additional
12 hour and part thereof to pay for
= 6 + 1
= 7
Amount to pay from 11.32 a.m. to 12.32 a.m. = $3
Amount to pay from 12.32 a.m. to 3.39 p.m. = 7 x 1.90 = $13.30
Total amount that Luis paid
= 3 + 13.30
= $16.30
Answer(s): $16.30
