Question 7: (0.5 points) Assume you were asked to prepare a table of compound interest factor values (like those in the back of this book) used in calculating the present worth of a geometric gradient series. Determine the two values for n = 1 and 2 for an interest rate of 10% per year and a rate of change g of 5% per year. Question 8: (0.5 points) An A&E firm planning for a future expansion deposited $40,000 each year for 5 years into a sinking (investment) fund that was to pay an unknown rate of return. If the account had a total of $451,000 immediately after the fifth deposit, what rate of return did the company make on these deposits?

Step 1
Question 7: The compound interest factor (F/P, g, i, n) is calculated using the formula: F/P = [(1 + i)^n - (1 + g)^n] / [i - g] Where: i = interest rate g = rate of change n = number of periods Show more…

1.A perpetuity pays $1,000 per year. If the appropriate interest rate is 5%: a. What is its present value if payment will begin 1 year from now? b. What would the value be if payments on the annuity began immediately?

Present value and Interest Rates/ what is the relationship between the value of an annuity and the level of interest rates? Suppose you just bought an eight-year annuity of $400 per year when interest rates are 10 percent per year. What happens to the value of your investment if interest rates suddenly drop to 6 percent? What if interest rates suddenly rise to 14 percent?
