The cost of admission to a popular music concert was $122 for 11 children and 3 adults. The admission was $102 for 6 children and 4 adults in for another group. How much was the admission for each child and adult?

Let the price of an adult's ticket = A

Let the price of a child's ticket = C

11C + 3A = 122.......................(1)

6C + 4A =102........................(2)

Now, you have 2 simultaneous equations. Can you solve them?
