12. a). The annuity payment formula is P = [r(PV)]/[ 1-(1+r)-n] where P is the payment, PV is the present value, r is the rate of interest per period and n is the number of periods.

Here, P = $ 30000, r =6.3/100 = 0.063 and n = 30. Hence 30000 = 0.063(PV) /[ (1-(1.063)-30] or, PV = (30000/0.063) [ (1-(1.063)-30] = (30000/0.063) * (1-0.159956563) = (30000/0.063)*0.840043436 = $ 400020.68 ( on rounding off to the nearest cent). Thus, $ 400020.68 will be needed at the beginning.

b). The money that will be withdrawn from the account will be 30*$ 30000 = $ 900000.

c). The part of the money withdrawn, which is interest is $ 900000- $ 400020.68 = $ 499979.32.
