You can put this solution on YOUR website!
Let w = the ounces of the silver of $16.60 per ounce.

Account for dollars per ounce.
Amount of alloy resulting was w+50.

highlight%28%2816.60%2Aw%2B15.20%2A50%29%2F%28w%2B50%29=16.10%29 which corresponds to placement of descriptions
(cost of alloy)/(amount of alloy)=(price per ounce of alloy)

Solve for w.
