Step-by-step explanation:

Answer 2

Answer: option C) y = 850 (1.050^x

Step-by-step explanation:

I recommend do some calculations of the rent duirng a few years to derive a law.

# of years elapsed rent
x y in $

0 (start) 850
1 850 * 1.05
2 850 * (1.05)^2
3 850 * (1.05)^3

With that you can infere the law: y = 850 * (1.05)^x

So, the answer is the option C)
