How much do you need to raise?

My team was a rookie team this year. We finished somewhere in 19th place. And we made to the quarterfinals.

Since we did well this year, my teacher wants us to travel to two regionals and the championship. We will most likely take around 40 ppl per trip.

So far, we have roughly 7,000 dollars set in stone from our sponsors. How much more money do we need? (By the way, we are from orlando, so the central florida regional won't cost much)
