Each group should have a newspaper with current stock quotations. Choose nine stocks that group members think would make good investments. Imagine that you invest \(\$ 10,000\) in each of these nine investments. Check the value of your stock each day over the next five weeks and then sell the nine stocks after five weeks. What is the group's profit or loss over the five-week period? Compare this figure with the profit or loss of other groups in your class for this activity.
Describe two disadvantages of leasing a car over buying one.
The unpaid balance of an installment loan is equal to the present value of the remaining payments. The unpaid balance, \(P\), is given by $$ P=P M T \frac{\left[1-\left(1+\frac{r}{n}\right)^{-n t}\right]}{\left(\frac{r}{n}\right)} $$ where \(P M T\) is the regular payment amount, \(r\) is the annual interest rate, \(n\) is the number of payments per year, and \(t\) is the number of years remaining in the loan. a. Use the loan payment formula to derive the unpaid balance formula. b. The price of a car is \(\$ 24,000\). You have saved \(20 \%\) of the price as a down payment. After the down payment, the balance is financed with a 5 -year loan at \(9 \%\). Determine the unpaid balance after three years. Round all calculations to the nearest dollar.
Suppose that you drive 15,000 miles per year and gas averages \(\$ 3.50\) per gallon. a. What will you save in annual fuel expenses by owning a hybrid car averaging 60 miles per gallon rather than an SUV averaging 15 miles per gallon? b. If you deposit your monthly fuel savings at the end of each month into an annuity that pays \(5.7 \%\) compounded monthly, how much will you have saved at the end of six years?
You would like to have \(\$ 4000\) in four years for a special vacation following college graduation by making deposits at the end of every six months in an annuity that pays \(7 \%\) compounded semiannually. a. How much should you deposit at the end of every six months? b. How much of the \(\$ 4000\) comes from deposits and how much comes from interest?
