Answer:

190 cm²

aivan3 [116]

Answer:

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

Step-by-step explanation:

The first equation (x + y = 1,000 ) shows that x + y equal to the number of seats in the auditorium. That means that they represent the number of tickets. In the second equation (75x + 100y = 25,000) x and y are being multiplied by the cost of their level ticket. So x represents the number of level 1 tickets; y represents the number of level 2 tickets.

hope this helps!
