$6000.@ 4% for 2 years

To calculate the interest earned on an investment of $6000 at a rate of 4% for 2 years, you can use the simple interest formula:

Interest = Principal × Rate × Time

Where:
- Principal is the initial amount invested ($6000)
- Rate is the interest rate per period (4% which can also be written as 0.04)
- Time is the number of periods the money is invested for (2 years)

Plugging the numbers into the formula, we get:

Interest = $6000 × 0.04 × 2

Calculating this, we find:

Interest = $480

Therefore, the interest earned on an investment of $6000 at a rate of 4% for 2 years would be $480.
