To find the number of containers of cookies you need to sell, let's set up an equation.

Let c represent the number of containers of cookies you need to sell.

The cost of ingredients to make the cookies is $28 and you charge $4 per container of cookies. So for every container sold, you earn $4 in profit.

To earn a total profit of $20, we can set up the equation:

4c = 28 + 20

Simplifying the equation, we have:

4c = 48

Now, to find the value of c, we divide both sides of the equation by 4:

c = 48/4

c = 12

Therefore, you need to sell 12 containers of cookies to earn a profit of $20.
