If $100,000 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) 10,000(1+x/100)^n  E) 100,000n(x/100)
I think answer D is for compound interest (which i assumed)   and answer 100,000n(x/100) is for simple interest because it is not compounding.
