A silversmith mixed 25g of a 70% silver alloy with 50g of a 15% silver alloy.
What is the percent concentration of the resulting alloy?
:
Let x = resulting percent concentration (in decimals)
:
Write amt of silver equation
.7(25) + .15(50) = x(25+50)
17.5 + 7.5 = 75x
25 = 75x
x =
x = .333; 33.3% silver is the resulting concentration
