Help Us Reach Our $400 Planetarium Goal

Hello. My science class is going to the planetarium at the science center on Thursday. It is 9 dollars a head to get into the science center. My goal is to take 30 students, 4 teachers, and a couple of parents. That is about 325 dollars. I was also planning to buy everyone some pizzas, which would cost around 75 dollars, taking us to the total goal of 400 dollars. We would really appreciate your help. Thank you.
