Ashford 5: – Week 4 – Discussion 1

Your initial discussion thread is due on Day 3 (Thursday) and you have until Day 7 (Monday) to respond to your classmates. Your grade will reflect both the quality of your initial post and the depth of your responses.

Initial   Investment

Read the following instructions in order to complete this discussion, and review the example of how to complete the math required for this assignment:

1. Think of something you want or need for which you      currently do not have the funds. It could be a vehicle, boat, horse,      jewelry, property, vacation, college fund, retirement money, or something      else. Pick something which cost somewhere between \$2000 and \$50,000.
2. On page 270 of Elementary and Intermediate Algebra      you will find the “Present Value Formula,” which computes how much money      you need to start with now to achieve a desired monetary goal. Assume you      will find an investment which promises somewhere between 5% and 10%      interest on your money and you want to purchase your desired item in 12      years. (Remember that the higher the return, usually the riskier the      investment, so think carefully before deciding on the interest rate.)
3. State the following in your discussion:
• The desired item
• How much it will cost in 12 years
• The interest rate you have chosen to go with from part       b
4. Set up the formula and work the computational steps one      by one, explaining how each step is worked, especially what the negative      exponent means. Explain what the answer means.
5. Does this formula look familiar to any other formulas      you are aware of? If so, which formula(s) and how is it similar?
6. Incorporate the following five math vocabulary words      into your discussion. Use bold font to emphasize the words in your      writing (Do not write definitions for the words; use them appropriately      in sentences describing your math work.):
• Power
• Reciprocal
• Negative exponent
• Position
• Rules of exponents

Your initial post should be 150-250 words in length. Respond to at least two of your classmates’ posts by Day 7 in at least a paragraph. Do you agree with how they used the vocabulary? Do their answers make sense?

Carefully review the Grading Rubric for the criteria that will be used to evaluate your discussion.
