You can put this solution on YOUR website!
Let a = #oz. of solution A
\n" ); document.write( "Then 60-a = # oz. solution B. Then
\n" ); document.write( "0.60a +0.85(60-a) = 0.70*60,
\n" ); document.write( "0.60a + 51 - 0.85a = 42,
\n" ); document.write( "-0.25a = -9,
\n" ); document.write( "a = 36 oz. of solution A, and 24 oz. of solution B. \n" ); document.write( "

\n" );
