Answer:

Step-by-step explanation:
Donna's Rate is 
Rico's Rate is 

Cross-Multiply



Donna's Rate is 
Rico's Rate is 

Child = $5.70
Adult = $9.80
- We can conclude that the amount of adult is double the amount of child tickets bought. (total of $556.60)
For this, you will need to divide the total amount by two and draw a tree chart with each of the numbers to get the seperation of the two. I would find out how many 9.80s or 5.70s go into $56.60 so you'll just have $500
