3484 tickets are adults tickets, which means that 1578 are under 18 tickets since 5062-3484=1578. Then you multiply 3484 by the price of the adult tickets and 1578 by the price of the under 18 tickets and add them together. 3484*18=62712, and 1578*12=18936. 62712+18936=81648. This means that in total, they made $81,648 in ticket sales. Then you have to find how much went to the community projects. 15% of ticket sales go to the community so $81,648*(0.15) equals $12,247.20
