$\"a\"$ = number of $8.50 brushes sold
\n" ); document.write( " $\"b\"$ = number of $9.75 brushes sold

\n" ); document.write( "(2) $\"850a+%2B+975b+=+38975\"$ (in cents)
\n" ); document.write( "Multiply both sides of (1) by $\"850\"$
\n" ); document.write( "and subtract from (2)
\n" ); document.write( "I'd do it, but I lost my calculator \n" ); document.write( "
