total mixture will be 100
\n" ); document.write( "we use x amount in the 70 % solution and 100-x in the 20% solution
\n" ); document.write( "70%=70/100
\n" ); document.write( "20%=20/100
\n" ); document.write( "50%=50/100
\n" ); document.write( "70x/100+20/100*(100-x)=50/100*(100)
\n" ); document.write( " \n" ); document.write( "
