could you aid with this

You bought a house worth $314,000. You paid 25% of the purchase price in cash and arranged a twenty-five-year mortgage with a rate of 4.5% compounded semi-annually for the remaining balance. The mortgage has an amortization period of 25 years. How much interest will you pay in the first 7 years (assuming that the first payment is made at the end of the first month)? In the first 7 years, you will pay $ in interest. (Round the final answer to the nearest cent as needed. Round effective rate to six decimals if desired as needed.)
