Delivery service package |
|
Load to be carried per lorry |
Mass not over 5000 kg |
Rental cost of 1 lorry with driver |
$90 per hour or part thereof |
The laundromat hired the delivery service from 2 p.m. to 4.10 p.m. Find the total amount that was paid for the delivery service.
Number of sets of 5000 kg
= 52270 ÷ 5000
= 10.454
Number of lorries needed to transport 52270 kg of inventory
= 10 + 1
= 11
From 2 p.m. to 4.10 p.m.: 2 h 10 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 90
= $270
Rental cost of 11 lorries with drivers for 3 h
= 11 x 270
= $2970
Answer(s): $2970
