First, you would need to create an equation for this problem.
[tex] \frac{4}{5} [/tex] = [tex] \frac{x}{2,000} [/tex]
Next, you would cross multiply.
5x = 8,000
Now, all you would have to do is isolate the x. To do this, you would divide both sides by 5.
x = 1,600
1,600 people are considered middle class.
I hope this helps!
