Algebra.Com's Answer #632792 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! Call the amount of 40% solution, x. \n" ); document.write( "Then the amount of 25% used is 128 - x. \n" ); document.write( "The set up looks like this: \n" ); document.write( "x(.40) + (128-x)(.25) = 128(.34) \n" ); document.write( ".4x + 32 - .25x = 43.52 \n" ); document.write( ".15x = 11.52 \n" ); document.write( "x = 11.52/.15 = 76.8 liters of 40% solution \n" ); document.write( "128-x = 51.2 L of 25% solution \n" ); document.write( " |
