1. When purchasing a home, you are offered an APR of 4.3% for a loan
within \$240,000 and \$300,000.
(a) Explicitly describe a unique example of taking out a fixed rate
mortgage installment loan for 30-years (i.e., how much is your
mortgage and what will your monthly payment be).
(b) Create an amortization table with the following headings: payment number, monthly payment, amount of monthly payment
applied towards interest, amount of monthly payment applied towards remaining balance, remaining balance, and equity. This
table should include all payments for the term of the mortgage.
(c) Create an accompanying chart which includes the remaining balance and the equity through the term of the mortgage. Appropriately labeled and large enough to view on its own.

money you would have paid at the end of your mortgage.

gets to see the chart and not the table. You could imagine you
are presenting this chart to someone who has not taken this course
yet.

of 5% of the balance.
(a) Describe a scenario of your further purchases made for the next

month 5 should exceed \$650 (refer to part (b)).
(b) Create a table in Excel to catalog your situation using the headings: month, previous balance, payments, purchases, finance charge,
and new balance.

to make no further purchases on the card and to pay only the
minimum required payment from now on. How many months
(from when you began paying only the minimum payment) will
it take for your balance to be under \$200? Discuss/explain your
solution, if you used logs, include the calculation in an appropriate
cell, if you are going to use a table, include the table, etc.
