The $75 per credit hour course fee tacked on to all the MBA
classes has generated a windfall of $56,250 in its first semester.
“Now we just need to make sure we spend it all,” the Assistant Dean
cackled. She charged the Graduate Curriculum Committee with
generating a shopping list before their next meeting. Four months
later, the chairman of the committee distributed the following. As
the professor for the quantitative modeling course, he tended to
think in terms of decision variables, so he added the left-most
column for ease of use.

Decision Variable	Item	Cost	Note
A	iPads for everybody	$750/unit	Must get a cover if these are purchased
B	iPad covers with MBA logo	$25/unit	Not needed unless we buy iPads
C	Speaker series	$15,000	Can’t afford both this and the iPads
D	Subscriptions to the Wall Street Journal	$10/unit	Don’t need if we have the electronic version
E	Subscriptions to the electronic version of the Wall Street Journal	$5/unit	Worthless without the iPads

1- Which of the constraints best describes the relationship between
the iPads for everyone and the speaker series?

		A – C = 1
		A + C = 2
		A – C = 0
		A + C = 1

2-Which of the following constraints best describes the
relationship between the electronic Wall Street
Journal subscription and the iPads?

		E – A = 0
		E – A = 1
		E – A = 1
		E – A = 0
