A laundromat hired a delivery service to move its machines to a new location. The mass of all its inventory 24450 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 3000 kg |
Rental cost of 1 lorry with driver |
$50 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 3000 kg
= 24450 ÷ 3000
= 8.15
Number of lorries needed to transport 24450 kg of inventory
= 8 + 1
= 9
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 50
= $150
Rental cost of 9 lorries with drivers for 3 h
= 9 x 150
= $1350
Answer(s): $1350
