◦Because of the super typhoon Yolanda, there was a big need for blood donors, medicines, doctors, nurses, medical aides, or any form of medical assistance. The Red Cross planned to involve different agencies, organizations, and offices, public and private, local and international, in their project to have massive medical services. The Red Cross contacted first three of the biggest networks, and each of these networks contacted three other networks, and agencies, organizations, and offices, and so on, until enough of these were contacted. It took one hour for an organization to contact three other organizations and all the contacts made were completed within 4 hours. Assume that no group was contacted twice. ◦1. Suppose you are one of the people in the Red Cross who visualized this project. How many organizations do you think were contacted in the last round? How many organizations were contacted within 4 hours?

◦2. Make a table to represent the number of organizations, agencies, and offices who could have been contacted in each round.

◦3. Write an equation to represent the situation. Let the independent variable be the number of rounds and the dependent variable be the number of organizations, agencies, and offices that were contacted in that round.

◦4. If another hour was used to contact more organizations, how many additional organizations, agencies, and offices could be contacted?
