A laundromat hired a delivery service to move its machines to a new location. The mass of all its inventory 27760 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 |
$90 per hour or part thereof |
The laundromat hired the delivery service from 2 p.m. to 3.40 p.m. Find the total amount that was paid for the delivery service.
Number of sets of 4000 kg
= 27760 ÷ 4000
= 6.94
Number of lorries needed to transport 27760 kg of inventory
= 6 + 1
= 7
From 2 p.m. to 3.40 p.m.: 1 h 40 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 90
= $180
Rental cost of 7 lorries with drivers for 2 h
= 7 x 180
= $1260
Answer(s): $1260
