Answer:

12.51%

Explanation:

after the first 6 years, you will have:

FV = PV (1 + r)ⁿ

  • PV = $8,500
  • r = 6%
  • n = 6

FV = $8,500 (1 + 6%)⁶ = $12,057.41

If you need to have $19,320 in 4 years, then you must determine r:

$19,320 = $12,057.41 (1 + r)⁴

$19,320 / $12,057.41 = (1 + r)⁴

1.6023 = (1 + r)⁴

⁴√1.6023 = 1 + r

1.1251 = 1 + r

1.1251 - 1 = r

0.1251 = r

r = 12.51%
