A laundromat hired a delivery service to move its machines to a new location. The mass of all its inventory 36600 kg. The load and rental cost of a lorry from the delivery service are seen in the table.
Delivery service package |
|
Load to be carried per lorry |
Mass not over 4000 kg |
Rental cost of 1 lorry with driver |
$40 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
= 36600 ÷ 4000
= 9.15
Number of lorries needed to transport 36600 kg of inventory
= 9 + 1
= 10
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 40
= $80
Rental cost of 10 lorries with drivers for 2 h
= 10 x 80
= $800
Answer(s): $800
