Find the equation for \"P\" = profit
\n" ); document.write( "and find \"P=0\", the break even point
\n" ); document.write( "Let \"t\" = number of T-shirts sold
\n" ); document.write( "\"+P+=+1099t+-+%28+28000+%2B+399t+%29+\" ( in cents )
\n" ); document.write( "Set \"+P=0+\"
\n" ); document.write( "\"+0+=+1099t+-+%28+28000+%2B+399t+%29+\"
\n" ); document.write( "\"+1099t+=+28000+%2B+399t+\"
\n" ); document.write( "\"+1099t+-+399t+=+28000+\"
\n" ); document.write( "\"+700t+=+28000+\"
\n" ); document.write( "\"+t+=+40+\"
\n" ); document.write( "They must sell 40 T-shirts to break even
\n" ); document.write( "
\n" );
