To determine how many bags of chips the soccer team needs to sell to raise $1,000.00, you can divide the total amount needed by the price per bag.
\[ \text{Number of bags} = \frac{\text{Total Amount}}{\text{Price per bag}} = \frac{1000.00}{2.50} \]
Calculating that gives:
\[ \frac{1000.00}{2.50} = 400 \]
So, the soccer team needs to sell 400 bags of chips to raise $1,000.00.
The correct answer is: 400 bags.
