A laundromat hired a delivery service to move its machines to a new location. The mass of all its inventory 21980 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 |
$100 per hour or part thereof |
The laundromat hired the delivery service from 1 p.m. to 3.40 p.m. Find the total amount that was paid for the delivery service.
Number of sets of 4000 kg
= 21980 ÷ 4000
= 5.495
Number of lorries needed to transport 21980 kg of inventory
= 5 + 1
= 6
From 1 p.m. to 3.40 p.m.: 2 h 40 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 100
= $300
Rental cost of 6 lorries with drivers for 3 h
= 6 x 300
= $1800
Answer(s): $1800
