how many gallons each of 25% alcohol and 35% alcohol should be mixed to get 10 gallons of 32% alcohol?
\n" ); document.write( "------------
\n" ); document.write( "Equation:
\n" ); document.write( "alcohol + alcohol = alcohol
\n" ); document.write( "0.25 x + 0.35(10-x) = 0.32*10
\n" ); document.write( "==================================
\n" ); document.write( "Multiply thru by 100 to get:
\n" ); document.write( "25x + 35*10 - 35x = 32*10
\n" ); document.write( "-10x = -3*10
\n" ); document.write( "x = 3 gallons (amt. of 25% alcohol needed in the mixture)
\n" ); document.write( "-----------
\n" ); document.write( "10-x = 7 gallons (amt. of 35% alcohol needed in the mixture)
\n" ); document.write( "==========================
