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 equation:
\[ \text{Number of bags} = \frac{\text{Total amount to raise}}{\text{Price per bag}} \]
Plugging in the values:
\[ \text{Number of bags} = \frac{1000}{2.50} \]
Calculating that gives:
\[ \text{Number of bags} = 400 \]
So, they would need to sell 400 bags of chips to raise $1,000.00.
The correct response is: 400 bags.
