Final answer:
The rate of return that your uncle would earn on his investment is 78.1%, which is not one of the given options.
Step-by-step explanation:
To calculate the rate of return on an investment, we can use the formula:
Rate of return = ((Future value - Present value) / Present value) * 100
In this case, the present value is $105,000 (the amount your uncle will pay for the annuity), and the future value is the sum of all the payments over the 11-year period, which is $17,000 * 11 = $187,000.
Plugging these values into the formula, we get:
Rate of return = ((187,000 - 105,000) / 105,000) * 100 = 78.1%
Therefore, the rate of return that your uncle would earn on his investment is 78.1%, which is not one of the given options.
