How many gallons of a 13%-salt solution must be mixed with 6 gallons of a 24%-salt solution to obtain a 16%-salt solution?
\n" ); document.write( "-------
\n" ); document.write( "Equation:
\n" ); document.write( "salt + salt = salt
\n" ); document.write( "0.24*6 + 0.13x = 0.16*(6+x)
\n" ); document.write( "----------
\n" ); document.write( "24*6 + 13x = 16*6 + 16x
\n" ); document.write( "3x = 8*6
\n" ); document.write( "x = 16 gallons (amt. of 13% solution needed)
