Answer: 6%
Explanation:
The annual payments can be considered to be annuity payments as they are constant. The amount borrowed can be considered the present value of the annuity.
Present value of annuity = Annuity * Present value interest factor of annuity, 8 years, %?
178,960 = 28,819 * Annuity factor
Annuity factor = 178,960 / 28,819
= 6.20979
To find out the interest rate, look at the Present Value of Annuity table and go to the 8 period column. Look for 6.20979. The interest rate that intersects with this factor is the interest rate implicit in this agreement.
That rate is 6%.
