A laundromat hired a delivery service to move its machines to a new location. The mass of all its inventory 59730 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 |
$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 5000 kg
= 59730 ÷ 5000
= 11.946
Number of lorries needed to transport 59730 kg of inventory
= 11 + 1
= 12
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 12 lorries with drivers for 2 h
= 12 x 80
= $960
Answer(s): $960
