All calculations are based on the assumption that $400 is the initial

investment. If that is not true,let

me know and I'll redo the cal. based

on the new INFO.

Pt = Po * (r + 1)^n

r = ((9 / 12)/ 100) * 6 = 0.045 = Semi-

annual rate expressed as a decimal

n = 2 yr. / 0.5 = 4 = The number of

compounding periods.

Pt = 400 * (0.045)^4 = 477.01 = The

value of the investment after 2 yrs.
