    Matrix Question

    A factory can produce three products, Widgets, Votsits, and Hummets, using parts A and B. To produce 1 Widget, it needs 2 units of A and 6 units of B. To produce 1 Votsit it needs 3 units of A and 1 unit of B. To produce 1 Hummet, 1 unit of A and 2 units of B are required.
    a) Construct a parts requirements matrix using parts as column headings. b) An order is received for 6 Widgets, 2 Votsits, and 7 Hummets. Use matrix multiplication to compute the total number of parts required.

    c) Giventhatthecostof1unitofAis$2andthecostof1unitofB is$3,findthetotalcost
    of the order by matrix multiplication.
