Answer:

19 years

Explanation:

The compound interest formula tells you the future value of principal P invested at annual rate r compounded n times per year for t years is ...

A = P(1 +r/n)^(nt)

Solving for t, we get ...

t = log(A/P)/(n·log(1 +r/n))

Using the given values, we find t to be ...

t = log(2.13022)/(4·log(1 +0.04/4)) ≈ 19.000

The investment will be worth $213,022 after 19 years.
