Given parameters:

Number of boxes Athena bought for the party  = x

Number of cookies per box = 10

Number of cookies she brought to the party = 70

Number removed  = 2 boxes

Unknown:

Equation of the number of boxes = ?

Solution:

    1 box of cookies contains 10 cookies

If Athena, removed 2 boxes, in those two boxes, we have 20 cookies

 Total number of cookies  = 70 + 20 = 90 cookies;

So;

    x  = [tex]\frac{total number of cookies}{number of cookies per box}[/tex]

   Therefore;

                    x  = [tex]\frac{90}{10}[/tex]boxes
