<PRE><B>Question 993223</B>
 A silversmith mixed 35 g of an 80% silver alloy with 40 g of a 25% silver alloy. What is the percent concentration of the resulting alloy? (Round your answer to one decimal place.) 
-----
Equation:
silver + silver = silver
-------
0.80*35 + 0.25*40 = x(75)
-------
80*35 + 25*40 = 7500x
------
x = 0.5067
--------
