1. New DS games (the big ones like Professor Layton/Pokemon/Zelda/etc.) will cost you $34.99 (not including tax)
2. A typical fast food meal (Entree, side, and a drink), will be anywhere from $5.50-$8.50, depending on the entree and if you want to "value size" (MOAR FRIES AND DRINK!) it. 
Have fun in DC, I haven't been there myself (even though I'm relatively close to it), but I've always wanted to go.
