I have two equations... I want to find the minimum number of years when S2>S1
S2= (10000(1.07^n -1)/(1.07-1))
I tried really really hard to solve this, but I ended up with some crap where n should be a negative number, which is impossible. The answer must be 6.33, btw)
I would very much appreciate it if anyone can help me out.
Thanks in advance
