In your own words, explain how compounding works. According to the rule of 72, if you deposit $100 in an account that pays 9% compound interest, how long will it take that initial deposit to reach $200? Use the matrix given below. For each type of investment, record this information: • Is the risk high, moderate, or low? • Is the return high, moderate, or low? • How does this type of investment work? Explain in one or two sentences.
Consider an investment that pays off $700 or $1,400 per $1,000 invested with equal probability. Suppose you have $1,000 but are willing to borrow to increase your expected return. What would happen to the expected value and standard deviation of the investment if you borrowed an additional $1,000 and invested a total of $2,000? What if you borrowed $2,000 to invest a total of $3,000? Instructions: Complete the table below to answer the questions above. Enter your responses as whole numbers and enter percentage values as percentages not decimals (i.e., 23% not 0.23). Enter a negative sign (-) to indicate a negative number if necessary. Invest $1,000 Invest $2,000 Invest $3,000 Expected Value $ 1050 1200 $ $ 1300 Percentage 20 % 30 % 40 % Standard Deviation 300 600 900 Expected Return N/A Doubled Tripled
1. Select one of the following questions to answer: If I invest $1000 at 3% interest, how long will take for my money to double? If I invest $1000 at 6% interest, how long will take for my money to double? If I invest $1000 at 8% interest, how long will take for my money to double?
