A government bond is bought for $5000 on June 1, 2010. The value of the bond increases each year by 3.9% of the previous year's value, and the bond matures on June 1, 2030. Determine the value of the bond at maturity.
I'm confused.

Calculus 
Steve,
The bond grows for 20 years, so you need to calculate the value after the 20th year. Since it grows by 3.9% per year, multiply each year's value by 1.039 to get the next year's value.
ding ding ding  use the growth factor formula: Tn = a r^(n1)
a=5000
n=20
r = 1.039
