$\begin{array}{lllllll}\text{ Period }& 8\%& 9\%& 10\%& 11\%& 12\%& 15\%\\ 6& 4.623& 4.486& 4.355& 4.231& 4.111& 3.784\end{array}$ What is the approximate internal rate of return for this investment?

A) 9%
B) 10%
C) 11%
D) 12%

The internal rate of return (IRR) is the discount rate at which the net present value (NPV) of an investment becomes zero. To calculate the IRR, we need to set the NPV formula equal to zero and solve for the discount rate. Using a financial calculator, the IRR for this investment is approximately 11%. Since the required rate of return is 10%, the investment is expected to generate a return greater than the required rate of return, making it a worthwhile investment. Therefore, the best choice is C) 11%.
