Delivery service package |
|
Load to be carried per lorry |
Mass not over 5000 kg |
Rental cost of 1 lorry with driver |
$50 per hour or part thereof |
The laundromat hired the delivery service from 5 p.m. to 6.10 p.m. Find the total amount that was paid for the delivery service.
Number of sets of 5000 kg
= 56880 ÷ 5000
= 11.376
Number of lorries needed to transport 56880 kg of inventory
= 11 + 1
= 12
From 5 p.m. to 6.10 p.m.: 1 h 10 min
Duration that each lorry would be rented for
= 1 + 1
= 2 h
Rental cost of 1 lorry with driver for 2 h
= 2 x 50
= $100
Rental cost of 12 lorries with drivers for 2 h
= 12 x 100
= $1200
Answer(s): $1200
