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 3 p.m. to 5.30 p.m. Find the total amount that was paid for the delivery service.
Number of sets of 5000 kg
= 59320 ÷ 5000
= 11.864
Number of lorries needed to transport 59320 kg of inventory
= 11 + 1
= 12
From 3 p.m. to 5.30 p.m.: 2 h 30 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 50
= $150
Rental cost of 12 lorries with drivers for 3 h
= 12 x 150
= $1800
Answer(s): $1800
