anonymous · Answer

if 3 pounds can feed 15 people,therefore 1 pound will feed 5 group of people..if there are 200 people, when they are in group of 5 ,it'll be 40 groups. So 40 pounds of potatoe-salad will feed 40groups which is 200people in general

anonymous · Answer

Right, basically divide 200 by 15 to find out how many groups of 15 you will need to feed, which is 13.3333....etc.
Then multiply 13.3333....by 3 to find the number of pounds for your 15 groups. This equals 40 pounds in total.
