Answer:
$15,533.69
Explanation:
the future value of your stock account = $900 x 1,490.48048 (FV annuity factor, 0.6667%, 360 periods) = $1,341,432.43
the future value of your bond account = $600 x 832.32019 (FV annuity factor, 0.4167%, 360 periods) = $499,392.11
after 30 years, the balance of your 2 accounts = $1,840,824.54
the monthly withdrawal = $1,840,824.54 / 118.50531 (PV annuity factor, 0.5%, 180 periods) = $15,533.69
