Answer:
37% compounded annually
Explanation:
To find the answer we need to follow this formula:
Where:
- P = Present value of the stock
- I = Initial value of the stock
- r = Interest rate
- n = number of compounding periods
Now we plug the amounts into the formula:
900,000 = 150,000 (1 + r)^13
900,000 / 150,000 = (1 + r)^13
60 = (1 + r)^13
Ln60 = 13 Ln(1 + r)
4.09 / 13 = Ln(1 +r)
0.31 = Ln(1 + r)
e0.31 = Ln(1 + r)
1.37 = 1 + r
1.37 - 1 = r
0.7 = r
Thus, the annual interest rate is 37%
