If they sold 89 calendars over 4 weeks, the 'equation' would look like (x = average calendars sold over 4 weeks):
![x = \frac{89}{4}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B89%7D%7B4%7D%20)
If you solve it, you get:
![22 \frac{1}{4}](https://tex.z-dn.net/?f=22%20%5Cfrac%7B1%7D%7B4%7D%20)
Which is equal to
22.25. Hope this helps!
