I have been considering refinancing my house. To do so, I will need to borrow $300,000. The loan period is 30 years and payments are made monthly. Several months ago I could have gotten a loan at 3% APR, but today the APR is 4%. How much additional interest will I pay over the life of the loan because of the interest rate increase? Select one: a. $60,276 b. $63,112 c. $71,206 d. $71,298 e. None of the above
