Step-by-step explanation:
Given: The ratio of child to teen to adult tickets sold at a water park on Saturday was 4:1:2.
Let the number of child tickets = 4x , teen tickets = x , adult tickets = 2x

![\Rightarrow\ x=\dfrac{294}{7}\\\\\Rightarrow\ x=42](https://tex.z-dn.net/?f=%5CRightarrow%5C%20x%3D%5Cdfrac%7B294%7D%7B7%7D%5C%5C%5C%5C%5CRightarrow%5C%20x%3D42)
