Final answer:
To find the number of bags Avery filled this week, divide the total amount of money he earned by the amount of money he earns for each bag. Avery filled 11 bags of leaves this week.
Step-by-step explanation:
To find the number of bags Avery filled this week, we can divide the total amount of money he earned by the amount of money he earns for each bag. Let's call the number of bags Avery filled 'x'.
From the given information, we have the equation: 2.25x = 24.75.
To solve for x, we can divide both sides of the equation by 2.25: x = 24.75 / 2.25 = 11.
Therefore, Avery filled 11 bags of leaves this week.
