Can someone help me with this? A silversmith mixed 25 g of an 80% silver alloy with 70 g of a 15% silver alloy. What is the percent concentration of the resulting alloy? (Round your answer to one decimal place.)

    20 is the Concentration of 80% silver alloy 10. 5 Is the concentration Of 15% silver alloy So what you do is add those amounts together and put it over the total grams of alloy mixed Total concentration of silver alloy OVER total grams of alloy

    Then simplify the fraction AS necessary, set it equal to x/100 and solve for x x represents the percent concentration of silver alloy in the mixture
