A linear programming computer package is needed.
Georgia Cabinets manufactures kitchen cabinets that are sold to local dealers throughout the Southeast. Because of a large
backlog of orders for oak and cherry cabinets, the company decided to contract with three smaller cabinetmakers to do the
final finishing operation. For the three cabinetmakers, the number of hours required to complete all the oak cabinets, the
number of hours required to complete all the cherry cabinets, the number of hours available for the final finishing
operation, and the cost per hour to perform the work are shown here.

For example, Cabinetmaker 1 estimates it will take 50 hours to complete all the oak cabinets and 60 hours to complete all
the cherry cabinets. However, Cabinetmaker 1 only has 40 hours available for the final finishing operation. Thus,
Cabinetmaker 1 can only complete 40/50 = 0.80, or 80%, of the oak cabinets if it worked only on oak cabinets. Similarly,
Cabinetmaker 1 can only complete 40/60 = 0.67, or 67%, of the cherry cabinets if it worked only on cherry cabinets.
(a) Formulate a linear programming model that can be used to determine the percentage of the oak cabinets and the
percentage of the cherry cabinets that should be given to each of the three cabinetmakers in order to minimize the
total cost of completing both projects. (Let 01 = percentage of oak cabinets assigned to cabinetmaker 1, 02 =
percentage of cak cabinets assigned to cabinetmaker 2, 03 = percentage of oak cabinets assigned to cabinetmaker
3, C1 = percentage of cherry cabinets assigned to cabinetmaker 1, C2 = percentage of cherry cabinets assigned to
cabinetmaker 2, and C3 = percentage of cherry cabinets assigned to cabinetmaker 3.)
