Question 1099870: Dan needs 4 lb of metal with 35 % silver. If Dan combines
one metal with 24 % silver, and another with 68
% silver, how much of each metal does Dan need? Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! Let n be the amount of 68% silver metal, and 4-n be the amount of 24% silver. Then:
.68n+.24(4-n)=.35(4)=1.4
.44n+.96=1.4
.44n=.44
n=1
Dan needs 1 lb of 68% silver metal, and 3 lbs. of 24% metal
