The equation representing the number of tickets sold is  .

Step-by-step explanation:

Let the number of child tickets = x and the number of adult tickets = y.

We have,

Cost of 1 child ticket = $4. So, the cost of x child tickets = 4x dollars.

Cost of 1 adult ticket = $6. So, the cost of y adult tickets = 6x dollars.

Since, the total revenue from the tickets = $420.

We get the equation,

Cost of x child tickets + Cost of y adult tickets = Total revenue

i.e.

Hence, the equation representing the number of tickets sold is  .
