Monthly, yearly, etc?

OpenStudy (anonymous):

someone said i had to times the interest and the percent and then times the year and i got 30 but it said the answer was wrong idk what im doing wrong..

jimthompson5910 (jim_thompson5910):

$30 is the amount of interest you earn in the 2 years You have to add that back onto the original balance of $500 to get 500+30 = 530 dollars

jimthompson5910 (jim_thompson5910):

keep in mind that this is using simple interest most banks use compound interest, but simple interest is a good place to start
