@princeton123211 is right, the flat rate taxi works out to about $100 to anywhere in Manhattan with tolls, fees, and tip. Uber can be a little less or could be quite a bit more. Nice thing about cabs is you follow the signs to the curb where they pick you up, while ubers require more walking to find their location
There are no "day passes" for the subway. Pay per ride or you can get a weekly pass that works out when you take 13 or so rides in a week
