A laundromat hired a delivery service to move its machines to a new location. The mass of all its inventory 39780 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 3000 kg |
Rental cost of 1 lorry with driver |
$70 per hour or part thereof |
The laundromat hired the delivery service from 4 p.m. to 5.30 p.m. Find the total amount that was paid for the delivery service.
Number of sets of 3000 kg
= 39780 ÷ 3000
= 13.26
Number of lorries needed to transport 39780 kg of inventory
= 13 + 1
= 14
From 4 p.m. to 5.30 p.m.: 1 h 30 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 70
= $140
Rental cost of 14 lorries with drivers for 2 h
= 14 x 140
= $1960
Answer(s): $1960
