Number Problem 14 Solution

This is the solution for the Algebra number word problem which was asked by an anonymous visitor that read, "55 bowls of the same size capacity of food.
1. everyone gets their own bowl of soup
2. every two gets one bowl of spaghetti to share
3. every three will get one bowl of salad
4. all r required to have their own helping of salad, spaghetti, and soup."

Ok you know the total number of people is x.  Since '" every two gets one bowl of spaghetti to share" then x/2 of the people will have those bowls and since "every three will get one bowl of salad" then x/3 of the people will have those bowls in which they will total 55 bowls. 
So we have:

x + x/2 + x/3 = 55  ** multiply by 6

6x + 3x + 2x = 330

11x = 330

x = 30

So there are 30 bowls for soup, 30/2 = 15 bowls for spaghetti , and 30/3 = 10 bowls for salad. 

Check 30 + 15 + 10 = 55

  1. There were 100 people present at a baseball card show:

    59 were men
    72 were football and baseball card collectors
    81 were college graduates
    89 were right-handed

    What is the least number of men who were both football and baseball card collectors and right-handed college graduates?
