The school that Heather goes to is selling tickets to the annual dance competition. On the first day of ticket sales the school sold 10 adults tickets and 8 child tickets. Find the price of an adult ticket and the price of a child ticket

Let the price of an adult ticket be A and the price of a child ticket be C.

From the given information, we know:
10A + 8C = total revenue on the first day of ticket sales.

Unfortunately, without more information about the total revenue or any ticket price relation between adult and child tickets, we cannot determine the exact values of A and C.
