If both the pork and burger are for the tacos/burritos, you will want fixings for 175. You go to the taco/potato bar for 100 and use 1 3/4 times the amount to get enough for 175.

The pig will serve about 1 person for each 3/4 to 1 pound of raw weight- there is a LOT of loss- you want enough beef to cover everyone else- probably about 100-125 servings. 1 pound of raw burger makes 3 -4 people's worth of tacos (depends on size of appetites, lesser number if it is teens, self serve, etc).
