You can put this solution on YOUR website!
Let $\"t\"$ = number of t-shirts you must sell
\n" ); document.write( " $\"1530+%2B+3t+=+20t\"$
\n" ); document.write( "This equation says
\n" ); document.write( "(money spent to make $\"t\"$ t-shirts) = (money made on $\"t\"$ t-shirts)
\n" ); document.write( " $\"17t+=+1530\"$
\n" ); document.write( " $\"t+=+90\"$
\n" ); document.write( "You must sell 90 t-shirts to break even \n" ); document.write( "
