A herd of dinosaurs made paintings in the sand with their claws. Each baby dinosaur made 15 paintings and each adult dinosaur ma
de 7 paintings. The entire herd made 208 paintings in total, and there were 3 times as many baby dinosaurs. How many baby dinosaurs and adult dinosaurs were there?
Let x = baby dinosaurs y = adult dinosaurs equation 1 total paintings = 15 painting x + 7 paintings y equation 2 baby dinosaurs = 3 times adult x= 3y substitute x= 3y to equation 1 y = 4 x = 12 There are 12 baby dinosaurs and 4 adult dinosaurs in a herd with 208 total paintings
