5.3 Annuities Consider a $110,000 mortgage loan with interest at 9% APR compounded monthly. – Draw a graph that shows how the term of the loan depends on the monthly payment amount. – What is the monthly payment amount required to pay off the loan in 15 years? – If you pay $500 more per month, how long will it take to pay off the loan? Consider a $180,000 mortgage 30 year loan with interest at 7.5% APR compounded monthly. – What is the monthly payment amount required to pay off the loan in 30 years? – If you pay the required monthly payment for 8 years and then pay $1250 more each month than the monthly payment until the loan is paid, how long will it take to pay off the house?

5.3 Annuities A $250,000 mortgage for 30 years at 6% APR. What will the monthly payments be? Suppose you make the required monthly payments for that same $250,000 mortgage for 12 years and then make payments of $ until the loan is paid. In how many years total will the mortgage be completely paid?
