Aherd 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. how many baby dinosaurs and adult dinosaurs were there?

Answers

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
