\n" ); document.write( "that is 55% salt. How many ounces of each solution should she use?

\n" ); document.write( "\n" ); document.write( "        Calculations in the post by @lwsshak3 are incorrect, giving wrong answer.\r
\n" ); document.write( "\n" ); document.write( "        I came to bring a correct solution.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solution A = x ounces
\n" ); document.write( "Solution B = (70-x) ounces
\n" ); document.write( "let x = Amt of solution A used
\n" ); document.write( "70-x = Amt of solution B used
\n" ); document.write( "0.45x + 0.7*(70-x) = 0.55*70
\n" ); document.write( "0.45x + 49 - 0.7x = 38.5
\n" ); document.write( "0.25x = 10.5
\n" ); document.write( "x = 10.5/0.25 = 42.
\n" ); document.write( "70-x = 28
\n" ); document.write( "Amt of solution A used = 42 ounces
\n" ); document.write( "Amt of solution B used = 28 ounces\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "CHECK   for the final concentration     \"%280.45%2A42+%2B+0.7%2A28%29%2F70\" = 0.55, or 55%.     ! precisely correct !\r
