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