Step-by-step explanation:
Answer:
There are a couple different solutions to your equation:

![x=\sqrt[22]{\frac{13}{n}}](https://tex.z-dn.net/?f=x%3D%5Csqrt%5B22%5D%7B%5Cfrac%7B13%7D%7Bn%7D%7D)
![x=-\sqrt[22]{\frac{13}{n}}](https://tex.z-dn.net/?f=x%3D-%5Csqrt%5B22%5D%7B%5Cfrac%7B13%7D%7Bn%7D%7D)

Okay to find percentages of things you have to take that original value (1500) and multuply it by the percentage. But when you multiply you put the percentage into a decimal and move it over to the right side two decimal places to the left. For example 10.0% would mean you need to multiply by 0.10 okay?
So for this problem you need to do 1500 *.013 and you get 19.5 computers.
