You can put this solution on YOUR website!
Let \"+a+\" = number of munchkins bought each month
\n" ); document.write( "Let \"+b+\" = number of regular donuts bought each month
\n" ); document.write( "----------------
\n" ); document.write( "(1) \"+a+%2B+b+=+62+\"
\n" ); document.write( "(2) \"+25a+%2B+100b+=+2450+\"
\n" ); document.write( "-------------------------
\n" ); document.write( "Multiply both sides of (1) by \"+25+\"
\n" ); document.write( "and subtract (1) from (2)
\n" ); document.write( "(2) \"+25a+%2B+100b+=+2450+\"
\n" ); document.write( "(1) \"+-25a+-+25b+=+-1550+\"
\n" ); document.write( "\"+75b+=+900+\"
\n" ); document.write( "\"+b+=+12+\"
\n" ); document.write( "and, since
\n" ); document.write( "(1) \"+a+%2B+b+=+62+\"
\n" ); document.write( "(1) \"+a+=+62+-+12+\"
\n" ); document.write( "(1) \"+a+=+50+\"
\n" ); document.write( "You bought 50 munchkins
\n" ); document.write( "You bought 12 regular donuts
\n" ); document.write( "
\n" ); document.write( "
\n" );
