Answer: -27/8
Step-by-step explanation:










This is a problem where you should make an equation.

First Week : x
Second Week : x + 5
Third Week : 2(x+5)
You need to add these up to make your equation. Your equation will look something like this :

Now you simplify.



That means they sold 104 Boxes in the First Week.

109 x 2 = 218
And they sold 218 Boxes the Third Week.
