A laundromat hired a delivery service to move its machines to a new location. The mass of all its inventory 31760 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 |
$80 per hour or part thereof |
The laundromat hired the delivery service from 5 p.m. to 6.10 p.m. Find the total amount that was paid for the delivery service.
Number of sets of 4000 kg
= 31760 ÷ 4000
= 7.94
Number of lorries needed to transport 31760 kg of inventory
= 7 + 1
= 8
From 5 p.m. to 6.10 p.m.: 1 h 10 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 80
= $160
Rental cost of 8 lorries with drivers for 2 h
= 8 x 160
= $1280
Answer(s): $1280
