A laundromat hired a delivery service to move its machines to a new location. The mass of all its inventory 26460 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 |
$120 per hour or part thereof |
The laundromat hired the delivery service from 1 p.m. to 3.30 p.m. Find the total amount that was paid for the delivery service.
Number of sets of 4000 kg
= 26460 ÷ 4000
= 6.615
Number of lorries needed to transport 26460 kg of inventory
= 6 + 1
= 7
From 1 p.m. to 3.30 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 120
= $360
Rental cost of 7 lorries with drivers for 3 h
= 7 x 360
= $2520
Answer(s): $2520
