A laundromat hired a delivery service to move its machines to a new location. The mass of all its inventory 47420 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 |
$70 per hour or part thereof |
The laundromat hired the delivery service from 3 p.m. to 5.30 p.m. Find the total amount that was paid for the delivery service.
Number of sets of 5000 kg
= 47420 ÷ 5000
= 9.484
Number of lorries needed to transport 47420 kg of inventory
= 9 + 1
= 10
From 3 p.m. to 5.30 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 10 lorries with drivers for 3 h
= 10 x 210
= $2100
Answer(s): $2100
