a broadway musical came to town. the auditorium filled all 1,000 seats at two-level pricing. level 1 tickets are $75 each, and level 2 tickets are $100 each. the theater made $25,000 from ticket sales. the system of equations that models this scenario is:

x + y = 1,000
75x + 100y = 25,000

what do the x and y represent in the system?

x represents the number of level 1 tickets; y represents the number of level 2 tickets
x represents the number of level 2 tickets; y represents the number of level 1 tickets
x represents the cost of level 1 tickets; y represents the cost of level 2 tickets
x represents the cost of level 2 tickets; y represents the cost of level 1 tickets
