Delivery service package |
|
Load to be carried per lorry |
Mass not over 5000 kg |
Rental cost of 1 lorry with driver |
$110 per hour or part thereof |
The laundromat hired the delivery service from 5 p.m. to 7.50 p.m. Find the total amount that was paid for the delivery service.
Number of sets of 5000 kg
= 57610 ÷ 5000
= 11.522
Number of lorries needed to transport 57610 kg of inventory
= 11 + 1
= 12
From 5 p.m. to 7.50 p.m.: 2 h 50 min
Duration that each lorry would be rented for
= 2 + 1
= 3 h
Rental cost of 1 lorry with driver for 3 h
= 3 x 110
= $330
Rental cost of 12 lorries with drivers for 3 h
= 12 x 330
= $3960
Answer(s): $3960
