You can put this solution on YOUR website!
The breakeven point comes when the cost equals the revenue. This is when you neither make nor lose money\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "R(x) = C(x)
\n" ); document.write( "12000x = 4000x+88000
\n" ); document.write( "12000x-4000x = 4000x+88000-4000x
\n" ); document.write( "8000x = 88000
\n" ); document.write( "8000x/8000 = 88000/8000
\n" ); document.write( "x = 11\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The breakeven point is at x = 11. So 11 units need to be sold to break even.
\n" ); document.write( "
\n" );
