1.1.10 (a) At an effective annual interest rate of 12%, calculate the number of years including fractions) it will take for an investment of 1000 to accumulate to 3000. (b) Repeat part (a) using the assumption that for fractions of a year, simple interest is applied. (c) Repeat part (a) using an effective monthly interest rate of 1%. (d) Suppose that an investment of 1000 accumulated to 3000 in exactly 10 years at effective annual rate of interest i. Calculate i (e) Repeat part (d) using an effective monthly rate of interest j. Calculate j
