Answer:
Interest rate of 7%.
Step-by-step explanation:
The compound interest formula is given by:

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
In this question:
We want to find t for which
when
. So



![\sqrt[10]{(1 + r)^10} = \sqrt[10]{2}](https://tex.z-dn.net/?f=%5Csqrt%5B10%5D%7B%281%20%2B%20r%29%5E10%7D%20%3D%20%5Csqrt%5B10%5D%7B2%7D)


So a interest rate of 7%.
