Value Mixture Problem

Question

A silversmith mixed 15 g of a 60% silver alloy with 70 g of a 25% silver alloy. What is the percent concentration of the resulting alloy? (Round your answer to one decimal place.)

Answer 1

0.6(15) + 0.25(70) = x(85)

9 + 17.5 = x(85)

26.5 =  x(85)

31.176 ≈ x

 

The resulting solution is approximately 31% silver alloy.
