let x be the number of ounces of the 25% solution
\n" ); document.write( ":
\n" ); document.write( "25% solution x 0.25 0.25x
\n" ); document.write( "30% solution 18 0.30 5.40
\n" ); document.write( "mixture x+18 0.26 0.26(x+18)
\n" ); document.write( ":
\n" ); document.write( "0.25x + 5.40 = 0.26 * (x + 18)
\n" ); document.write( ":
\n" ); document.write( "0.25x + 5.40 = 0.26x + 4.68
\n" ); document.write( ":
\n" ); document.write( "0.01x = 0.72
\n" ); document.write( ":
\n" ); document.write( "x = 72
\n" ); document.write( ":
