Harrington Corporation produces three products, A, B, and C. Pertinent information on these products is as follows:

Product	Selling Price per Unit			Variable Cost per Unit			Fixed Cost per Unit			DL Hours per Unit
A	$	4.00		$	1.00		$	2.00		2
B	$	3.50		$	0.50		$	2.00		2
C	$	6.00		$	2.00		$	3.00		3

The objective function for a linear program to maximize contribution margin from the set of three products is:

Multiple Choice

• Z = A + B + C.

• Z = $3A + $3B + $4C.

• Z = A + $0.50B + $2C.

• Z = $3A + $2.50B + $5C.

• Z = $4A + $3.50B + $6C.
