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? $$ \begin{array}{|l|l|l|l|} \hline \$ ? \text { at the end of each month } & 8.25 \% \text { compounded monthly } & 40 \text { years } & \$ 1,500,000 \\ \hline \end{array} $$
In Exercises 25-30, round to the nearest dollar. Suppose that you earned a bachelor's degree and now you're teaching high school. The school district offers teachers the opportunity to take a year off to earn a master's degree. To achieve this goal, you deposit \(\$ 2000\) at the end of each year in an annuity that pays \(7.5 \%\) compounded annually. a. How much will you have saved at the end of 5 years? b. Find the interest.

Suppose that you are thinking about buying a car and have narrowed down your choices to two options: The new-car option: The new car costs \(\$ 28,000\) and can be financed with a four-year loan at \(6.12 \%\). The used-car option: A three-year old model of the same car costs \(\$ 16,000\) and can be financed with a four-year loan at \(6.86 \%\). What is the difference in monthly payments between financing the new car and financing the used car?
