value: 6.25 points With a Series EE bond, you pay a particular amount today of, say, $25, and the bond accrues interest over the time you hold it. In early 2012, the U.S. Treasury promised to pay .60 percent per year on EE savings bonds. In an interesting (and important) wrinkle, if you hold the bond for 20 years, the Treasury promises to "step up" the value to double your cost. That is, if the $25 bond you purchased and all the accumulated interest earned is worth less than $50, the Treasury will automatically increase the value of the bond to $50. Required: (a) Assuming you purchased a $50 face value bond, what rate of return would you earn if you held the bond for 20 years until it doubled in value? (Round your answer as directed, but do not use rounded numbers in intermediate calculations. Enter your answer as a percent rounded to 2 decimal places (e.g., 32.16).) Rate of return (b) If you purchased a $50 face value bond in early 2012 at the then current interest rate of .60 percent per year, how much would the bond be worth in 2022? (Round your answer as directed, but do not use rounded numbers in intermediate calculations. Round your answer to 2 decimal places (e.g. 32.16).) Bond value (c) In 2022, instead of cashing the bond in for its then current value, you decide to hold the bond until it doubles in face value in 2032. What rate of return will you earn over the last 10 years? (Enter rounded answer as directed, but do not use rounded numbers in intermediate calculations. Enter your answer as a percent rounded to 2 decimal places (e.g., 32.16).) Rate of return
