12 quart of x solution mixed with 3 quarts of 1 solution (1 is 100%, it's 100% water)
\n" ); document.write( "So our total will be 12+3 = 15 and we want a 0.52 solution
\n" ); document.write( ":
\n" ); document.write( "12x+3(1) = 15(0.52)
\n" ); document.write( "12x+3 = 7.8
\n" ); document.write( "12x = 4.8
\n" ); document.write( "x = 0.4
\n" ); document.write( "the 12 quarts are a 40% solution
\n" ); document.write( "
\n" );
