Answer:
$16,014.64
Step-by-step explanation:
first we have to determine the present value of the last five years:
effective interest for last 5 years = (1 + 9%/4)⁴ - 1 = 1.093 - 1 = 9.31%
9.31% / 12 = 0.7757%
present value = $225 x 47.82377 (PV annuity factor, 0.7757%, 60 periods) = $10,760.35
now, present value = $10,760.35 / (1 + effective interest)³
effective interest first 3 years = (1 + 7%/12)¹² - 1 = 1.0723 - 1 = 7.23%
present value = $10,760.35 / (1 + 7.23%)³ = $8,727.25
now we need to determine the present value of the first 3 years:
present value = $225 x 32.38838 (PV annuity factor, 2.25%, 36 periods) = $7,287.39
total value of the annuity = $16,014.64
