A laundromat hired a delivery service to move its machines to a new location. The mass of all its inventory 45240 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 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
= 45240 ÷ 4000
= 11.31
Number of lorries needed to transport 45240 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 70
= $210
Rental cost of 12 lorries with drivers for 3 h
= 12 x 210
= $2520
Answer(s): $2520
