If $1000,000 is invested at x percent simple annual interest for n years, which of the following represents the total amount of interest, in dollars, that will be earned by this investment in the n years?  Choose the most appropriate option.
A) 10,000(x^n)
B) 10,000(x/100)^n
C) 10,000n(x/100)
D) 1,000,000n(x/100)
E) 10,000n(1+x/100)
I think answer 1,000,000n(x/100) is for compound interest (which i assumed)   and answer 1,000,000n(x/100) is for simple interest because it is not compounding.
