Delivery service package |
|
Load to be carried per lorry |
Mass not over 4000 kg |
Rental cost of 1 lorry with driver |
$110 per hour or part thereof |
The laundromat hired the delivery service from 4 p.m. to 5.20 p.m. Find the total amount that was paid for the delivery service.
Number of sets of 4000 kg
= 41920 ÷ 4000
= 10.48
Number of lorries needed to transport 41920 kg of inventory
= 10 + 1
= 11
From 4 p.m. to 5.20 p.m.: 1 h 20 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 110
= $220
Rental cost of 11 lorries with drivers for 2 h
= 11 x 220
= $2420
Answer(s): $2420
