Let x be the number of pairs of the first type.

\n" ); document.write( "The number she bought of the second type was 20 more than one-half of that number: (1/2)x+20.

\n" ); document.write( "The first type cost $22 a pair; the total cost of them was \"22%28x%29\".
\n" ); document.write( "The second type cost $26 a pair; the total cost of them was \"26%28%281%2F2%29x%2B20%29\".

\n" ); document.write( "The total cost of the first type was 110 more than the total cost of the second type:
\n" ); document.write( "\"22x+=+26%28%281%2F2%29x%2B20%29%2B110\"
\n" ); document.write( "\"22x+=+13x%2B520%2B110\"
\n" ); document.write( "\"9x+=+630\"
\n" ); document.write( "\"x+=+70\"

\n" ); document.write( "She bought 70 pairs of the first type.
\n" ); document.write( "The number of pairs of the second type that she bought was (1/2)*70+20 = 55.
\n" ); document.write( "
\n" );
