1.	A feasible region has vertices at (4, 6), (-2, 3), (2, -2), and (3, 1). At which point is the maximum value of the function f(x, y) = 2x + y?
		A.	f(2, -2)	B.	f(3, 1)
		C.	f(-2, 3)	D.	f(4, 6)
		Hint
	2.	Find the minimum value of f(x, y) = 4x - 2y for the polygonal region determined by the feasible region.
		A.	-28	B.	27
		C.	-14	D.	14
		Hint
	3.	Selena has 31 days to complete her quilt for the county fair. The blue squares in the quilt can be sewn at a rate of 4 squares per day, and the white squares at a rate of 7 squares per day. The quilt can have up to 96 squares total. The blue fabric b costs about $0.80 per square and the white fabric w costs about $1.20 per square. Selena wants to keep costs at a minimum. Write the function that describes the cost of the quilt.
		A.	96 = 0.80b + 1.20w
		B.	f(b, w) = 0.80b + 1.20w
		C.	96 = 4b + 7w
		D.	f(b, w) = 4b + 7w
		Hint
	4.	Selena has 31 days to complete her quilt for the county fair. The blue squares in the quilt can be sewn at a rate of 4 squares per day, and the white squares at a rate of 7 squares per day. The quilt can have up to 96 squares total. The blue fabric b costs about $0.80 per square and the white fabric w costs about $1.20 per square. Selena wants to keep costs at a minimum. Write an inequality that expresses the total number of squares to be sewn.
		A.		B.
		C.		D.
		Hint
	5.	A baker earns 15¢ profit per glazed doughnut g, and 40¢ profit per jelly doughnut j. If a customer wants to buy no more than a dozen doughnuts and wants to try at least one of each kind, what is the maximum profit the baker can earn?
		A.	$3.30	B.	$4.80
		C.	$1.80	D.	$4.55
