Well lets work it out: If you were feeding a person a steak, it would be an 8-10 oz streak you would give them but with roast beef you would cut this thinner and give them more vegetables. Thus lets say you allow 4 oz per person (1/4 of a pound), then you would need 75/4 or 18.75 pounds of sliced beef. Thus to be sure you have enough you need to order between 20 and 25 pounds of sliced beef. But be sure you ask for it to be sliced thinly!!
