Answer:

  • 12 babies
  • 4 adults

Step-by-step explanation:

Let x represent the number of adult dinosaurs. Then 3x is the number of babies. The total number of paintings is ...

  15(3x) +7(x) = 208

  52x = 208 . . . . . . . . . simplify

  x = 4 . . . . . . . . . . . divide by 52

  3x = 4·3 = 12

There were 12 baby dinosaurs and 4 adult dinosaurs.
