Let x = the # of bags she initially sold.
\n" ); document.write( "==> Total sales was 52x initially. The total sales after selling 4 more bags is 4*$72 = $288\r
\n" ); document.write( "\n" ); document.write( "==> \"%2852x+%2B+288%29%2F%28x+%2B+4%29+=+57\"\r
\n" ); document.write( "\n" ); document.write( "==> 52x + 288 = 57(x + 4)
\n" ); document.write( "==> 52x + 288 = 57x + 228
\n" ); document.write( "==> 60 = 5x ==> x = 12, the number of bags initially sold.
\n" ); document.write( "Thus, x + 4 = 12 + 4 = 16 bags sold all in all.
\n" ); document.write( "
\n" );
