Final answer:
The annual payment for the mortgage is approximately $15,447.97.
Step-by-step explanation:
To calculate the annual payment for the mortgage, we can use the formula for the present value of an annuity. The present value (PV) is the initial loan amount, the interest rate (r) is 6% per year, and the number of periods (n) is 30 years. By plugging these values into the formula, we can calculate the annual payment (A):
A = PV x r / (1 - (1 + r)^(-n))
Substituting in the values, we get:
A = $257,000 x 0.06 / (1 - (1 + 0.06)^(-30))
Solving this equation, the annual payment for the mortgage is approximately $15,447.97.
