Question 469394: Anne and Nacny use a metal alloy that is 21% copper to make jewelry. How many ounces of 20% alloy must be mixed with a 24% alloy to form 96 ounces of the desire alloy? Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! m+n=96
.20m+.24n=.21(96)=20.16
20m+24n=2016
20m+20n=1920
4n=96
n=24
m=72
Anne and Nancy need 72 oz. of 20% alloy, and 24 oz. of 24% alloy to make the desired silver..
