Hello, I need help answering this review question:

Problem 2

• Loan 1: $200,000 at 4.5% for 30 years, monthly payments, and no origination cost. APR = 4.80%
• Loan 2: $200,000 at 4.25% for 30 years, monthly payments, and no origination cost.

Questions:

1. What is the discount point charged on Loan 1 assuming there is no cost associated with the origination?
2. How many points must be charged on the 2^ndloan to equalize the APR on the two loans?
