Three adult and three child movie tickets were purchased for $75. The cost of each child’s ticket is three dollars less than the cost of an adult ticket. Find the price of each ticket.

Let's say the cost of an adult ticket is A dollars.
So the cost of a child's ticket is A - 3 dollars.
The cost of the 3 adult tickets is 3A dollars.
The cost of the 3 child tickets is 3(A - 3) = 3A - 9 dollars.
The total cost of the tickets is 3A + 3A - 9 = 6A - 9 dollars.
Since the total cost is $75, we have:
6A - 9 = 75
Adding 9 to both sides, we get:
6A = 84
Dividing both sides by 6, we have:
A = 14
So the cost of an adult ticket is $14, and the cost of a child's ticket is $14 - $3 = $11. Answer: \boxed{14, 11}.
