Answer:
$12000 at 5% 
$27000 at 6.5%.
Step-by-step explanation:
Let x represent amount invested at 5% and y represent amount invested at 6.5%.
We have been given that a combined total of 39000 is invested in two bonds. We can represent this information in an equation as:

We are also told that the annual interest rate is 2355.00. We can represent this information in an equation as:

Upon substituting equation (1) in equation (2), we will get:







Therefore, an amount of $12,000 is invested at 5%.
Upon substituting  in equation (1), we will get:
 in equation (1), we will get:



Therefore, an amount of $27,000 is invested at 6.5%.
