    A. (5, 4) B. (2, 4)
    C. (5, 1) D. (0, 6)
    Hint

  2.   Find the minimum value of f(x, y) = 4x - 2y for the polygonal region determined by the feasible region.
   
    A. -14 B. -28

    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. f(b, w) = 4b + 7w
    B. 96 = 4b + 7w
    C. f(b, w) = 0.80b + 1.20w
    D. 96 = 0.80b + 1.20w
    Hint
