Have decided to buy a new home that costs $300,000. They want to
make a 20% down payment and finance the rest. Their bank has offered to lower the
quoted interest rate of 4.75% by 0.125% per point. Each point will cost 1% of the amount
borrowed. Trystan and Kendall will buy 2 points. What will it cost to buy the 2 points to
lower the interest rate to 4.5%?
