Final answer:
To calculate the interest rate, we need to find the present value of the stream of payments and compare it to the initial investment. For the next 10 years, the interest rate is approximately 5.93%.
Step-by-step explanation:
To calculate the interest rate, we need to find the present value of the stream of payments and compare it to the initial investment. Let's calculate the interest rate for each scenario:
For the next 10 years:
The present value of the stream of payments is $13,000, and the annual payment is $2,300 for 10 years.
Using the present value formula, we can calculate the interest rate:
PV = PMT * ((1 - (1 + r)^(-n)) / r)
$13,000 = $2,300 * ((1 - (1 + r)^(-10)) / r)
This equation can be solved using financial calculators or software to find that the interest rate is approximately 5.93%.
