Question

Leach Distributors packages and distributes industrial supplies. A standard shipment can be packaged in a class A container, a class K container, or a class T container. A single class A container yields a profit of

$6;

a class K container, a profit of

$10;

and a class T container, a profit of

$8.

Each shipment prepared requires a certain amount of packing material and a certain amount of time.

Formulate and solve this problem using LP software.

Decision variables:

X1=number

of class A containers to be used

X2=number

of class K containers to be used

X3=number

of class T containers to be used

Resources Needed per Standard Shipment

Class of Container	Packing Material (pounds)	Packing Time (hours)
A	2		2
K	1		6
T	3		4
Total amount of resource available per week	180	pounds	240	hours

Hugh Leach, head of the firm, must decide the optimal number of each class of container to pack each week. He is bound by the previously mentioned resource restrictions but also decides that he must keep his
