A historical fact

One of the key elements of this course is to help students understand and appreciate the role of mathematics in their everyday life. We use numbers and place-value nearly every day. Let's celebrate some of the historical numbers systems that have developed into our base-10 number system today.

Discussion Topic: Describe an interesting aspect of Mayan civilization that we did not discuss in class. Your findings must come from some source such as an encyclopedia, article, or internet site and you must provide reference(s) of the materials you used (either the publishing information or Internet address).

Assignment: Using a reputable source of your choice, post one historical fact about the Mayan Civilization. It would be best if it is related to their number systems or the Mayan Calendar, but anything interesting will work.

1. Post one unique historical fact about the Mayan Civilization.

2. Think about your financial future and at what age you expect to retire. The Internal Revenue Service recently announced that employees in 401(k) plans will be able to contribute up to $20,500 in the year 2022.

3. The million-dollar question! Suppose you want to have $1,250,000 for retirement in 30 years. If you deposit the same amount each month into an annuity that earns 6% interest annually (and compounded monthly), what is the amount you need to deposit each month? Show your work using the formula.

4. What is amortization?

5. Suppose you want to buy a car. The dealer offers a financing package consisting of a 4.6% APR compounded monthly for a term of five years. Suppose that you want your monthly payments to be at most $499. What is the maximum amount that you should finance? (Show your work using the formula and Round your answer to the nearest dollar.)
