Q: Alden's family invited their relatives for a family reunion on Christmas eve. There were 50 more female adults than male adults, and children were twice the total number of adults. If there were 100 male adults, how many people attended the family reunion?
A:
If the number of female adults was 50 more than the males, then there were 100 + 50 = 150 females. The total number of adults is 150 + 100 = 250. The children were twice the total number of adults, thus 2 * 250 = 500. The total number of people at the family reunion is 500 + 250 = 750. The answer is 750.
