    1. The problem statement, all variables and given/known data
    An investor wants to purchase one investment among common stocks, preferred stocks and bonds of six industries located in several countries. The investor can use a full-service broker or a discount broker and can buy with cash or margin. If there are 288 possible choices, how many countries is the investor considering?

    2. Relevant equations

    3. The attempt at a solution
    Well there are 6 industries, each industries has a stock or bond to invest in. Then there are 2 broker choices and afterwards, 2 ways to pay.

    so i used this equation to solve for the amount of countries there were...


    solved for X which came out to be 6 but it was wrong. Can anyone tell what factors I've missed?
