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

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)
