2.45x+2.30(30-x)=2.35*30
\n" ); document.write( "2.45x+69-2.30x=70.5
\n" ); document.write( ".15x=70.5-69
\n" ); document.write( ".15x=1.5
\n" ); document.write( "x=1.5/.15
\n" ); document.write( "x=10 pounds of the $2.45 mix is used.
\n" ); document.write( "30-10=20 pounds of the 42.30 mix ix used.
\n" ); document.write( "Proof:
\n" ); document.write( "2.45*10+2.30*20=2.35*30
\n" ); document.write( "24.5+46=70.5
\n" ); document.write( "70.5=70.5
\n" ); document.write( "
