I need to get 500 gallons of a 34% mixture but I only have 5oo gallons of a 25% mixture and 500 gallons of a 50% mixture what is the formula to mix? Thank you
\n" ); document.write( "---------------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "Quantity Equation:::::x + y = 500
\n" ); document.write( "Active Ingredient Eq::0.25x + 0.50y = 0.34*500
\n" ); document.write( "---------------------------------
\n" ); document.write( "25x + 25y = 25*500
\n" ); document.write( "25x + 50y = 34*500
\n" ); document.write( "------------------------------
\n" ); document.write( "25y = 9*500
\n" ); document.write( "y = 180 gallons (amt of 50% solution needed in the mixture)
\n" ); document.write( "----
\n" ); document.write( "x + y = 500
\n" ); document.write( "x + 180 = 500
\n" ); document.write( "x = 320 gallons (amt of 25% solution needed in the mixture)
\n" ); document.write( "===============================
