Questions 1-3 illustrate a really useful framework for solving this type of problem. When you're using an algebraic formule
it's ALWAYS a good idea to clearly identify the information that you're given, as well as what it is you're being asked to find.
Then you can plug that information into the known formula and solve the resulting equation.
4. After receiving an inheritance, a newly married couple invested $15,250 for 10 years and received $9,150 in simple
interest. What was the rate that the investment paid? Use the framework from Questions 1–3, and show all of your work.
Write your answer in the form of a sentence.
15,25 ()!1c)21345
5. If that couple had been able to find an investment that paid 9% interest, how much more quickly would they have made
that $9,150 in simple interest? Use the framework from Questions 1–3, and show all of your work. Write your answer in
the form of a sentence.
