Step 1 :Let's denote the amount invested at 4% as x and the amount invested at 8% as y.
Step 2 :We know that the total amount invested is $22,000, so we can write the equation as \(x + y = 22000\).
Step 3 :We also know that the total interest earned is $1,080, so we can write another equation as \(0.04x + 0.08y = 1080\).
Step 4 :We can solve this system of equations to find the values of x and y.
Step 5 :The solution to the system of equations is \(x = 17000\) and \(y = 5000\).
Step 6 :Final Answer: Ms. Suzuki invested \(\boxed{17000}\) dollars at 4% and \(\boxed{5000}\) dollars at 8%.
