Let G represent the number of Grandparents. There were twice as many parents as grandparents: Let 2G represent the number of Parents 50 more children than parents. Let 2G + 50 represent the Children ---------------------------- G + P + C = 400 Solve this equation for G: G + 2G + 2G + 50 + 400 @marcelie Post what you get, okay?

This above G + 2G + 2G + 50 + 400 should be G + 2G + 2G + 50 = 400 G + 2G + 2G + 50 + 400 5G + 50 = 400 5*G = 350
