First, you would need to create an equation for this problem.

=

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 = <span>
1,6001,600 people are considered middle class. I hope this helps!</span>
Let would be the annual interest rate such that,
I = P x r^t
For the 1st
160.67 = (2000) x r*8/12 ; r = 0.02277
The second case is just the same.
Answer:
B
Step-by-step explanation:
idk I think its correct
The ^3 and ^2 are exponents sorry I don’t think you can type exponents on a keyboard, 6x^3+22x^2+3x-6
