Given a vector

x = [400 800 1200]

You can multiply it with the interest factor to get individual interests

x_interest = x*0.025;

and calculate total interest

interest_total = sum(x_interest)

Yes, you can just write these lines in a function. Since this is a homework problem, so I cannot give an exact answer but here is a useful link
