how many ounces of a 35% alcohol solution must be mixed with 17 ounces of a 40% alcohol solution to make 36% alcohol solution?
\n" ); document.write( "-----------------
\n" ); document.write( "Equation:
\n" ); document.write( "alcohol + alcohol = alcohol
\n" ); document.write( "0.40*17 + 0.35x = 0.36(17+x)
\n" ); document.write( "-----
\n" ); document.write( "Multiply thru by 100 to get:
\n" ); document.write( "40*17 + 35x = 36*17 + 36x
\n" ); document.write( "x = 4*17
\n" ); document.write( "---
\n" ); document.write( "x = 68 ounces (amt. of 35% solution needed for the mixture)
\n" ); document.write( "==============================================================
