18/20=K/110
20K= 110*18
20K= 1980
K= 99
-9 to 0 is 9 and 0 to 14 is 14.
Total distance = 9 +14 = 23
This is a problem where you should make an equation.
Let's say x is the first week. It would mean
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.
So they sold 109 Boxes the Second Week.
109 x 2 = 218
And they sold 218 Boxes the Third Week.
