To find out how many bags of chips the soccer team needs to sell to raise $1,000.00 at $2.50 per bag, you can use the following calculation:
Total amount to raise / Price per bag = Number of bags needed
So,
\[ \text{Number of bags} = \frac{1000}{2.50} = 400 \]
Therefore, they need to sell 400 bags to raise $1,000.00.
The correct response is 400 bags.
