You deposit $5,000 in an account earning 7.5% interest compounded semiannually. How much will you have in the account after 9 years?

Question

(Note: Use n=12 for monthly compounding, n=4 for quarterly compounding, n=2 for semiannual compounding, and n=1 for annual compounding.)

Answer 1

amount=5000(1+ (i/n))^(t*n)
where n is the number of compounds per year, and t=9

for instance, for n=12, put this in your google search window:
5000(1+(.075/12))^(9*12)=

And the answer pops up 9799.56
