Answer:
617000
Step-by-step explanation:
Division reverses multiplication.
If the total population of Charlotte which we'll call 'x' follows
x * 0.05 = 30850, then
30850 / 0.05 = x
x = 617000
The correct answer would be 6.
To figure this out, you take the square root of 36 since area of a square is side x side.
