A laundromat hired a delivery service to move its machines to a new location. The mass of all its inventory 47400 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 |
$40 per hour or part thereof |
The laundromat hired the delivery service from 4 p.m. to 6.30 p.m. Find the total amount that was paid for the delivery service.
Number of sets of 4000 kg
= 47400 ÷ 4000
= 11.85
Number of lorries needed to transport 47400 kg of inventory
= 11 + 1
= 12
From 4 p.m. to 6.30 p.m.: 2 h 30 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 40
= $120
Rental cost of 12 lorries with drivers for 3 h
= 12 x 120
= $1440
Answer(s): $1440
