Answer:

  1500(1.0115)^(2t)

Step-by-step explanation:

The formula for the balance in an account earning compound interest is ...

  A = P(1 +r/n)^(nt)

where P is the principal invested, r is the annual rate, n is the number of times per year interest is compounded, and t is the number of years.

__

Using the given values in the formula, we have ...

  A = 1500(1 +0.023/2)^(2t)

Simplifying a bit, this is ...

  A = 1500(1.0115)^(2t) . . . . . CD value after t years
