Answer:

31 years

Explanation:

we have to prepare two future value equations:

  • FV = $8,000 x (1 + 0.0233)ⁿ
  • FV = $2,000 x (1 + 0.07)ⁿ

next we must equal them:

$8,000 x (1 + 0.0233)ⁿ = $2,000 x (1 + 0.07)ⁿ

4 x (1 + 0.0233)ⁿ = (1 + 0.07)ⁿ

4 = 1.07ⁿ / 1.0233ⁿ = (1.07 / 1.0233)ⁿ

4 = 1.0456367ⁿ

log4 = n x log1.0456367

0.602 = n x 0.01938

n = 0.602 / 0.01938 = 31.06 ≈ 31 years
