A laundromat hired a delivery service to move its machines to a new location. The mass of all its inventory 53600 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 |
$100 per hour or part thereof |
The laundromat hired the delivery service from 2 p.m. to 4.30 p.m. Find the total amount that was paid for the delivery service.
Number of sets of 4000 kg
= 53600 ÷ 4000
= 13.4
Number of lorries needed to transport 53600 kg of inventory
= 13 + 1
= 14
From 2 p.m. to 4.30 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 100
= $300
Rental cost of 14 lorries with drivers for 3 h
= 14 x 300
= $4200
Answer(s): $4200
