I trying to solve the following question. I want to know have i calculated Amy's part correctly or not?

The question is:

Amy deposited $1000 into an account that earns 8% annual interest compounded every 6 months. Bod deposited $1000 into an account that earns 8% annual interest compounded quarterly. If neither Amy nor Bob makes any additional deposits or withdrawals in 6 months, how much more money will Bob have in his account than Amy?

For Amy:

P=1000, t=1, n=2, r=4%

V=1000(1+0.04)^2

Somebody please guide me.

Zulfi.
