A 4% salt solution is mixed with a 16% salt solution. How many milliliters of each solution are needed to obtain 600 millilters of a 10% solution?
\n" ); document.write( ".
\n" ); document.write( "Let x = amount of 4% salt solution
\n" ); document.write( "then
\n" ); document.write( "600-x = amount of 16% salt solution
\n" ); document.write( ".
\n" ); document.write( ".04(x) + .16(600-x) = .10(600)
\n" ); document.write( ".04x + 96 - .16x = 60
\n" ); document.write( "96 - .12x = 60
\n" ); document.write( "96 - 60 = .12x
\n" ); document.write( "36 = .12x
\n" ); document.write( "300 milliliters of 4% salt solution = x
\n" ); document.write( ".
\n" ); document.write( "600-x = 600-300 = 300 milliliters of 16% salt solution
\n" ); document.write( "
\n" ); document.write( "
\n" );
