    Ratio of Nickel to Zinc:

    (2/7) = (Nickel / 4.9)

    Nickel = 1.4 lbs.

    Ratio of Copper to Zinc:

    (9/7) = (Copper / 4.9)

    Copper = 6.3 lbs.

    Alloy = Zinc + Nickel + Copper

    Alloy = 4.9 lbs. + 1.4 lbs. + 6.3 lbs.

    Alloy = 12.6 lbs.

    Hope this answer will be a good h elp for you.
