Answer:
11 years.
Explanation:
Below is the calculation for the time period:
Present value of the money = $6500
Interest rate = 3%
Future value of the money = $9000
Future value = Present Value (1 + r )^n
9000 = 6500 (1 + 3%)^n
9000/6500 = (1 + 3%)^n
1.3846 = (1.03)^n
Now solve for the value of n by taking ln on both sides.
Thus n = 11 years.
