A laundromat hired a delivery service to move its machines to a new location. The mass of all its inventory 54210 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 |
$100 per hour or part thereof |
The laundromat hired the delivery service from 1 p.m. to 2.50 p.m. Find the total amount that was paid for the delivery service.
Number of sets of 3000 kg
= 54210 ÷ 3000
= 18.07
Number of lorries needed to transport 54210 kg of inventory
= 18 + 1
= 19
From 1 p.m. to 2.50 p.m.: 1 h 50 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 100
= $200
Rental cost of 19 lorries with drivers for 2 h
= 19 x 200
= $3800
Answer(s): $3800
