Scraped the rear side of a Lexus RX330 (05)... how much would it cost to fix it?

[cloud thoughts]

I was backing out and on the turn I bumped my front bumper and scraped the rear side of a white lexus rx330 (05 model)... some scrapes and some color came off, no dents... its about 12x5... I was willing to pay off for the damages and I was wondering how much would it usually cost to fix it at the dealer?

If they want to paint the whole bumper it will probably cost about $300-400.
