# Math 221 week 4 DQ 1

Ashford 5: – Week 4 – Discussion 1

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: 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.
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.)
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 2
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.
Does this formula look familiar to any other formulas        you are aware of? If so, which formula(s) and how is it similar?
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. 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.
