The answer would be 200 because you would solve the equation 5.50+700=9n. Once you do, you end up with 200. And if you plug it in it equals the same.
        
                    
             
        
        
        
Answer:
90 different ways
Step-by-step explanation:
We have a total of 10 members, and we want to find how many groups of 2 members we can have, where the order of each member in the group of 2 is important, so we have a permutation problem.
To solve this problem, we need to calculate a permutation of 10 choose 2.
The formula for a permutation of n choose p is:

So we have:



So there are 90 different ways of choosing a president and a vice-president.
