If he invests $1,000 today as a lump sum in a bank account that compounds interest quarterly, what annual interest rate will he need in order to achieve his goal?

Randy and Rhoda just got married and found their dream home. They will need to take out a loan of $96,000 to pay for the home, as they have a $24,000 down payment. Randy and Rhoda qualify for their loan at 4% for 30 years. Randy and Rhoda have the opportunity to purchase 2 points to lower their interest rate to 2%.   How much will they save in interest by paying for points?
