Algebra.Com's Answer #68180 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! A silversmith mixed 30 g of a 60% silver alloy with 70 g of a 20% silver alloy. What is the percent concentration of the resulting alloy? \n" ); document.write( ": \n" ); document.write( "This is typical mixture problem, learn this method and you can do most of them. \n" ); document.write( ": \n" ); document.write( "We know that amt of the resulting alloy will be the total of the two inputs \n" ); document.write( "30 + 70 = 100 gram \n" ); document.write( ": \n" ); document.write( "Convert % to decimals \n" ); document.write( ": \n" ); document.write( "Let x = per cent (in decimals) of the resulting alloy: \n" ); document.write( ": \n" ); document.write( ".60(30) + .20(70) = x(100) \n" ); document.write( "18 + 14 = 100x \n" ); document.write( "32 = 100x \n" ); document.write( "x = 32/100 = .32 = 32% \n" ); document.write( ": \n" ); document.write( "Pretty easy, right? \n" ); document.write( " |
