How much does it cost to replace a rear bumper on a Ford Focus?

The rear bumper in my 2011 Ford Focus is a little cracked. How much would that cost to replace?|||well new 150 but you need to paint it maybe 200 but it well be easier to fix it|||depending on the damage if you know how to use Bondo fiberglass a sander and a paint gun you could do it yourself or buy the hole bumper at a salvage yard or off Ebay.
