Answer:
I think the answer is f' (x)=v
1st year 500* 0.03 = 15+500=515
2nd year 515*0.03= 15.45 + 515 = 530.45
3rd year 530.45*0.03= 15.9135 + 530.45 = 546.3635
4th year 546.3635 * 0.03 = 16.390905 + 546.3635 = 562.754405
562.754405
To solve this just put a 1 over the 15. So it would be 12/7 + 15/1 which is 16 5/7.
