Step 1 :Let's denote the amount invested at 11% as x and the amount invested at 6% as y. We know that the total amount invested is $17,818, so we have the equation \(x + y = 17818\).
Step 2 :We also know that the interest earned from the amount invested at 11% exceeds the interest earned from the amount invested at 6% by $490.33. This gives us the equation \(0.11x - 0.06y = 490.33\).
Step 3 :We can solve this system of equations to find the values of x and y.
Step 4 :The solution to the system of equations gives us the amounts invested at each rate. The amount invested at 11% is $9173 and the amount invested at 6% is $8645.
Step 5 :Final Answer: The amount invested at 11% is \$9173 and the amount invested at 6% is \$8645. So, the final answer is \(\boxed{9173, 8645}\).
