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?

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

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
