This is the way I read it:
\n" ); document.write( "Let \"+c+\" = the cost of the desktop
\n" ); document.write( "\"+c+-+400+\" = the cost of the laptop
\n" ); document.write( "--------------------------------
\n" ); document.write( "\"+.085c+%2B+.05%2A%28+c+-+400+%29+=+412+\"
\n" ); document.write( "\"+.085c+%2B+.05c+-+20+=+412+\"
\n" ); document.write( "\"+.135c+=+432+\"
\n" ); document.write( "\"+c+=+3200+\"
\n" ); document.write( "\"+c+-+400+=+2800+\"
\n" ); document.write( "-------------------
\n" ); document.write( "The cost of the desktop before finance charges is $3,200
\n" ); document.write( "The cost of the laptop before finance charges is $2,800
\n" ); document.write( "
\n" ); document.write( "
