Answer:

$395.74

Explanation:

the college fund requires 20 equal semiannual payments starting January 1, 2011 and the last one should be made on July 1, 2020.

first we must determine the effective rate of the fund:

effective rate = (1 + 10%/2)² - 1 = 10.25%

now we must determine the quarterly rate:

quarterly rate = (1 + r)¹/⁴ - 1 = 2.47%

the present value of the annuity:

PV = distribution x annuity factor

  • distribution = $1,000
  • PV annuity factor, 2.47%, 16 periods = 13.08553

PV = $1,000 x 13.08553 = $13,085.53

that means that by July 1, 2020, you need to have $13,085.53 in your college fund

FV of an annuity = contribution x annuity factor

  • FV = $13,085.53
  • FV annuity factor, 5%, 20 periods = 33.066

contribution = FV / annuity factor = $13,085.53 / 33.066 = $395.74
