Delivery service package |
|
Load to be carried per lorry |
Mass not over 3000 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 3000 kg
= 38910 ÷ 3000
= 12.97
Number of lorries needed to transport 38910 kg of inventory
= 12 + 1
= 13
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 13 lorries with drivers for 2 h
= 13 x 100
= $1300
Answer(s): $1300
