2400*[[1+(8%/3)]^4-1]=234

No...ans is 197...
i got my mistake...was missing one term in the formula

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

A = 2400 ( 1 + 8/300)^3
= 2597

So 2597 - 2400 = 197
Thanks neways!

What's the quickest way to calculate this:

A = 2400 ( 1 + 8/300)^3

Thanks!
