Answer:

Mr. Garden's investment has an annual interest rate of 8%

Step-by-step explanation:

To calculate the annual interest rate, we can use the formula:

Annual Interest Rate = (Annual Interest / Principal) * 100

In this case, the principal is $500,000 and the annual interest is $40,000.

Substituting these values into the formula, we get:

Annual Interest Rate = (40,000 / 500,000) * 100

Simplifying the expression:

Annual Interest Rate = 0.08 * 100

Therefore, the annual interest rate is 8%.
