Answer:
wow
Step-by-step explanation:
Start by calling the unknown amount 'x'. We can then set up a relationship to represent the question:
![213 = (30\%) \times x](https://tex.z-dn.net/?f=213%20%3D%20%2830%5C%25%29%20%5Ctimes%20x)
or
![213=0.3x](https://tex.z-dn.net/?f=213%3D0.3x)
and then solve for x, by dividing both sides of our equation by 0.3
![\frac{213}{0.3}=\frac{0.3x}{0.3}](https://tex.z-dn.net/?f=%5Cfrac%7B213%7D%7B0.3%7D%3D%5Cfrac%7B0.3x%7D%7B0.3%7D)
![710=x](https://tex.z-dn.net/?f=710%3Dx)
213 is 30% of 710
To check:
Just read what it says not that hard go to the left twice and go up 4 units.
Hope you have a good day
