Make Sense? In Exercises 23-26, determine whether each statement makes sense or does not make sense, and explain your reasoning. There must be an error in the loan amortization schedule for my mortgage because the annual interest rate is only \(3.5 \%\), yet the schedule shows that I'm paying more on interest than on the principal for many of my payments.
In Exercises 1-10, a. Find the value of each annuity. Round to the nearest dollar b. Find the interest. $$ \begin{array}{|l|l|l|} \hline \begin{array}{l} \$ 4000 \text { at the end of } \\ \text { each year } \end{array} & \begin{array}{l} 5.5 \% \text { compounded } \\ \text { annually } \end{array} & 40 \text { years } \\ \hline \end{array} $$
If an investor sees that the return from dividends for a stock is lower than the return for a no-risk bank account, should the stock be sold and the money placed in the bank account? Explain your answer.
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?
In Exercises 11-18, a. Determine the periodic deposit. Round up to the nearest dollar. b. How much of the financial goal comes from deposits and how much comes from interest? $$ \begin{array}{|l|l|l|l|} \hline \$ ? \text { at the end of each month } & 7.5 \% \text { compounded monthly } & 10 \text { years } & \$ 250,000 \\ \hline \end{array} $$
