A laundromat hired a delivery service to move its machines to a new location. The mass of all its inventory 20720 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 5000 kg |
Rental cost of 1 lorry with driver |
$60 per hour or part thereof |
The laundromat hired the delivery service from 3 p.m. to 5.50 p.m. Find the total amount that was paid for the delivery service.
Number of sets of 5000 kg
= 20720 ÷ 5000
= 4.144
Number of lorries needed to transport 20720 kg of inventory
= 4 + 1
= 5
From 3 p.m. to 5.50 p.m.: 2 h 50 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 60
= $180
Rental cost of 5 lorries with drivers for 3 h
= 5 x 180
= $900
Answer(s): $900
