Question 328117
To solve this problem, you need to write 2 equations using what you know.
First, you know that movie tickets for an adult and 3 children cost $20. This can be written as:
A + 3C = 20  (where A = price for an adult ticket, C = price for child's ticket)
Second, you know that an adult's ticket costs $2 more than a child's ticket:
A = C + 2
This can also be written as C = A - 2
Now plug the second equation into the first and solve for A:
A + 3C = 20
A + 3(A - 2) = 20
A + 3A - 6 = 20
4A - 6 = 20
4A = 26
A = 6.5
So the price of an adult ticket is $6.50
