Question 1 ( 5 points) The Peaceful Pelican Inn has four front desk workers. Three of them have been there exactly 10 years. One of them, named Hannah, was hired this year. What is the annual turnover percentage for this year? A

Step 1 ：The annual turnover percentage is calculated by dividing the number of employees who left during the year by the total number of employees at the start of the year, then multiplying by 100. In this case, only one employee (Hannah) was hired this year, which means one employee must have left. The total number of employees at the start of the year was 4. So, the annual turnover percentage is \((1/4)*100\).

Step 2 ：Final Answer: The annual turnover percentage for this year is \(\boxed{25\%}\).
