A herd of dinosaurs made paintings in the sand with their claws.
Each baby dinosaur made 15 paintings and each adult dinosaur made 7 paintings. The entire herd made 208 paintings in total, and there were 3 times as many baby dinosaurs as adult dinosaurs.
How many baby dinosaurs and adult dinosaurs were there?

Let's use X to represent adult dinos and 3X to represent baby dinos. 

 

Our equation is 7X + 3X(15) = 208. Simplifying, we have 52X = 208. If we divide both sides by 52, we are left with X = 4.

 

If X = 4, then 3X = 12. 

 

There are 12 baby dinos and 4 adult dinos.

 

Hope this helps,
