Your base fare will probably be $14.00 - $17.00.
If you are not time sensitive, Metro might work. You will want to take the Yellow Line and transfer at Gallery Place to the Red Line.
Or Blue Line and change at Metro Station. Just be prepared for long escalator and/or elevator rides in the stations.
