Over 25 years, Jared's saving bond has earned $500.00 in simple interest at a rate of 5%. How much was the original bond worth?

Nearly nothing

 

 

 

J.K

 

500=x(1.05)^25

500/x=(1.05)^25

1.05^25 = 3.3863549408993848

500=3.3863549408993848x

500/3.3863549408993848 = 147.6513858488810945106

round

$147.65

500/25=$20 interest per year

$20/.05=$400 price of original bond.
