the formula is
interest = prt 
Math tutor verify this  Chopsticks, Tuesday, March 10, 2009 at 5:38pm
The compound interest formula is:
A = P(1+r/n)^nt
P = principal amount (the initial amount you borrow or deposit)
r = annual rate of interest (as a decimal)
t = number of years the amount is deposited or borrowed for.
A = amount of money accumulated after n years, including interest.
n = number of times the interest is compounded per year
8000(1+.08)^1*3

Chopsticks is right  Reiny, Tuesday, March 10, 2009 at 5:43pm
8000(1+.08)^1*3
= 8000(1.08)^3
= 10077.70

Chopsticks is right. It is compounded annually. PRT is no compounding.
