Algebra.Com's Answer #639599 by fractalier(6550) You can put this solution on YOUR website! Call the amount of 25% solution, x. Then the amount of 75% solution would have to be 90-x. The setup is like this... \n" ); document.write( ".25x + .75(90-x) = .35(90) \n" ); document.write( "Now solve this... \n" ); document.write( ".25x + 67.5 - .75x = 31.5 \n" ); document.write( "-.5x = -36 \n" ); document.write( "x = 72 ounces of 25% solution which means \n" ); document.write( "90-x = 18 ounces of 75% solution \n" ); document.write( " |
