Top bond fund. An investment of $10,000 in the Emerging Country Debt Fund in 2001 was worth $24,780 in 2006 (www.money.com). Use the formula from the previous exercise to find the 5-year average annual return.
The formula is r=(s/p)^1/n -1
the -1 is after the rt 1/n to the right but on the same level as the (s/p) I hope that makes sense.
r=investment on annual return
S=value after n years
P=initial investment
n=number of years
