Diego bought 4 boxes of cookies to thank his coaches at the end of the season. Each box had the same number of cookies. A friend brought 1 cookie to add to each box. Now there were 28 cookies in all. What is the unknown amount in the story?

Respuesta :

Answer:

there are 24 cookies in the 4 boxes

there are 6 cookies in each box

Step-by-step explanation:

Let x = number of cookies in each box

If there are 4 boxes, the total number of cookies in the four boxes are 4x

If a friend brought 1 cookie to add to each box, the friend brought a total of 4 cookies

4x + 4 = 28

Solving for x

4x = 28 - 4

4x = 24

x = 6

Each box contains 6 cookies and there are 24 cookies in 4 boxes
