There are 200 adults and 300 children at a zoo. the zoo makes a total of $7000 from the entrance fees, and the cost for an adult and a child to attend is $30. write a system of equations that corresponds to the situation. do not solve.

200a+300c=7000

a+c=30

Try#1

200 adults. 300 children. 7000$. Do not solve. Equations.

Since the cost for a child AND an adult is 30$, then it is 15$ for a child, and 15$. I tried it and it does not make sense. So

Try#2

Let c be the cost of children and a be the cost for adults.

200a+300c=7000

a+c=30

This is all I can do.
