Your school is sponsoring a pancake dinner to raise money for a field trip. You estimate that 150 adults and 280 children will attend. Let x represent the cost of an adult ticket and y represent the cost of a child ticket. If the goal is to raise $1310, which of the given equations may be used to represent this situation?

280x + 150y =1310

150x + 280y =1310

430x =1310

150x =1310 + 280y
