Question 932205: An alloy is a mixture of metals. Suppose that a certain alloy is made by mixing
110
grams of an alloy containing
16%
copper with
210
grams of an alloy containing
64%
copper
(a) How many grams of copper are in the resulting mixture?
(b) What percentage of the resulting mixture is copper?
Answer by TimothyLamb(4379)   (Show Source):
You can put this solution on YOUR website! grams of copper are in the resulting mixture:
---
100*0.16 + 210*0.64 = 150.4 g
---
percent copper in the resulting mixture:
---
150.4/(100 + 210) * 100 = 48.52%
