Question: The Hickory Cabinet and Furniture Company produces sofas, tables, and chairs at its plant in Greensboro, North Carolina.

The plant uses three main resources to make furniture--wood, upholstery, and labor. The resources requirements for each

piece of furniture and the total resources available weekly are as follows:

Resource Requirements

Wood (lb) Upholstery (yd) Labor (hr.)

Sofa 7 12 6

Table 5 - 9

Chair 4 7 5

Total available resources 2250 1000 240

The furniture is produced on a weekly basis and stored in a warehouse until the end of the week when it is shipped out. The warehouse has a total capacity of 650 pieces of furniture. Each sofa earns $400 in profit, each table, $275, and each chair, $190.
