Answer:
$7,813.52
Explanation:
future value = quarterly contribution x annuity factor
quarterly contribution = $520
total quarterly contributions = 3 x 4 = 12 periods
interest rate = 16% / 4 = 4% compounded quarterly
future value annuity factor, 4%, 12 periods = 15.026
future value = $520 x 15.026 = $7,813.52
