A laundromat hired a delivery service to move its machines to a new location. The mass of all its inventory 26790 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 |
$120 per hour or part thereof |
The laundromat hired the delivery service from 4 p.m. to 5.40 p.m. Find the total amount that was paid for the delivery service.
Number of sets of 5000 kg
= 26790 ÷ 5000
= 5.358
Number of lorries needed to transport 26790 kg of inventory
= 5 + 1
= 6
From 4 p.m. to 5.40 p.m.: 1 h 40 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 120
= $240
Rental cost of 6 lorries with drivers for 2 h
= 6 x 240
= $1440
Answer(s): $1440
