To determine how much more the community center needs to raise, we need to add up the start-up costs associated with the youth soccer program and then subtract the amount they have already raised.
However, since the list of materials and their costs is not provided in your message, I'm unable to calculate the exact amount they need to raise.
Please provide the total start-up cost or the costs of materials, and I'll be able to calculate how much more they need to raise based on the $9,500 they have already collected.
