A. Pt = Po(1+r)^n,

r = 6.5% / 4 = 1.625% = 0.01625 = Quarterly % rate expressed as adecimal.

n = 4 comp./yr * 1 yr = 4 compounding
periods.

Pt = 12,000(1.01625)^4 = $12,799.22.

B. APY = I/Po.

I=Pt - Po = 12,799.22 - 12,000 = 799.22
= Interest.

APY=(799.22/12000)*100% = 6.66%.=Annual
Percentage Yield.
Formula: APY = (Pt-Po) / Po
