Answer: The annual interest rate r= 8%

Step-by-step explanation:

Given: The invested amount = $500,000.

The annual interest = $40,000

The annual interest rate is given by :-

$r=\frac{\text{interest}}{\text{invested amount}}\times100\\\\\Rightarrow\ r=\frac{40,000}{500,000}\times100\\\Rightarrow\ r=\frac{4}{50}\times100\\\\\Rightarrow\ r=8\%$
