A laundromat hired a delivery service to move its machines to a new location. The mass of all its inventory 51900 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 |
$70 per hour or part thereof |
The laundromat hired the delivery service from 2 p.m. to 3.20 p.m. Find the total amount that was paid for the delivery service.
Number of sets of 4000 kg
= 51900 ÷ 4000
= 12.975
Number of lorries needed to transport 51900 kg of inventory
= 12 + 1
= 13
From 2 p.m. to 3.20 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 70
= $140
Rental cost of 13 lorries with drivers for 2 h
= 13 x 140
= $1820
Answer(s): $1820
