Answer:
2X - Y + 3Z
Step-by-step explanation:
Combine like terms. Like terms are terms that have the same variable part.
6X + 5Y − 2Z − 4X − 6Y + 5Z =
= 6X - 4X + 5Y - 6Y - 2Z + 5Z
= 2X - Y + 3Z

First I found the number of adults by multiplying .60 by 700. It was 420. From there all I had to do was subtract it from 700. Revealing the number of children to be 280.
To get the answer, divide the receipts by 2 to get the total cost for adults and divide it again to get the total number of parents who attended
Cost for adults is $480.00
Number of adults is 240
Now, to get the children, subtract the total number of people by the number of adults.
620-240=380
Number of children is 380
