Answer:

$31,341.81

Step-by-step explanation:

The compound amount equation is A = P(1 + r/n)^(nt), where P is the unknown principal, r is the annual interest rate, n is the number of compounding periods per year and t is the number of years.  We want to solve this for P:

       A

------------------- = P

(1 + r/n)^(nt)

Substituting the given numerical values;

     $45,000

 ---------------------------  =  P

   (1+0.073/4)^(4*5)

Using a calculator, we evaluate this expression, obtaining:  $31,341.81
