Annie is renting an apartment and sees in the rental agreement that each year they will raise the rent by 5%. The rent when she first signs the agreement is $850. What function best models the amount of rent she will have to pay in each future year?A) y = 50x + 850 B) y = 850x + 50 C) y = 850(1.05)x D) y = 850(0.05)x
Question
Answer:
Answer: option C) y = 850 (1.050^xExplanation:
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)
