1) A store offers two payment plans. Under the installment plan, you pay 20% down and 20% of the purchase price in each of the next 4 years. If you pay the entire bill immediately, you can take a 5% discount from the purchase price. a. Calculate the present value of the payments, if you can borrow or lend funds at a 7% interest rate. Assume the product sells for $100. (Do not round intermediate calculations. Round your answer to 2 decimal places.) Present value $

2) Home loans typically involve “points,” which are fees charged by the lender. Each point charged means that the borrower must pay 1% of the loan amount as a fee. For example, if the loan is for $170,000 and 4 points are charged, the loan repayment schedule is calculated on a $170,000 loan but the net amount the borrower receives is only $163,200. What is the effective annual interest rate charged on such a loan assuming loan repayment occurs over 156 months? Assume the interest rate is .75% per month. (Do not round intermediate calculations. Round your answer to 2 decimal places.) Effective annual interest rate % 
3) Suppose you take out a $1,000, 4year loan using addon interest with a quoted interest rate of 23.25% per year.
a. What will your monthly payments be? (Total payments are $1,000 + $1,000 × .2325 × 4 = $1,930.) (Do not round intermediate calculations. Round your answer to 2 decimal places.)

b. What are the true APR and effective annual rate on this loan? (Do not round intermediate calculations. Round your answers to 3 decimal places.)

4) In a discount interest loan, you pay the interest payment up front. For example, if a 1year loan is stated as $28,000 and the interest rate is 22.25%, the borrower “pays” 0.2225 × $28,000 = $6,230 immediately, thereby receiving net funds of $21,770 and repaying $28,000 in a year. What is the effective annual rate on a 1year loan with an interest rate quoted on a discount basis of 22.25%? (Do not round intermediate calculations. Round your answer to 2 decimal places.)

You believe you will need to have saved $520,000 by the time you retire in 40 years in order to live comfortably. If the interest rate is 5% per year, how much must you save each year to meet your retirement goal? (Do not round intermediate calculations. Round your answer to 2 decimal places.)

Your consulting firm will produce cash flows of $110,000 this year, and you expect cash flow to keep pace with any increase in the general level of prices. The interest rate currently is 6.2%, and you anticipate inflation of about 2.2%.
a. What is the present value of your firm’s cash flows for years 1 through 6? (Do not round intermediate calculations. Round your answer to 2 decimal places.)
