	2.	Josh has 40 minutes to complete a government exam. There are 15 multiple-choice questions worth 3 points each. There are also 5 short-answer questions worth 11 points each. It takes about 2 minutes for Josh to answer the multiple-choice questions m and about 8 minutes to complete the short-answer questions s. The system of inequalities that represents this problem is graphed below. Which ordered pair is not a vertex of the feasible region?
		A.	(15, 0)	B.	(0, 5)
		C.	(20, 0)	D.	(0, 0)
		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.	96 = 4b + 7w
		C.	f(b, w) = 0.80b + 1.20w
		D.	f(b, w) = 4b + 7w
		Hint
