    a. P = Po(1+r)^n.
Po = $500.
r = 0.045/yr. = Annual % rate.
n = 1Comp/yr. * 11yrs. = 11Compounding periods.
b. r = 0.045/yr. * 0.5yr. = 0.0225 = Semi-annual % rate.
n = 2Comp./yr. * 11yrs. = 22 Compounding periods.
c. r = 0.045/yr. * 0.25yr. = 0.01125 = Quarterly % rate.
n = 4Comp./yr. * 11yrs. = 44 Compounding periods.

    d. P = Po*e^rt.
P/Po = e^rt.
r*t = 0.045/yr. * 11yrs. = 0.495,
e^0.495 = P/Po,
1.6305 = P/500, P = $820.25.
