Question

.

Answer 1

If it were just the lower level tickets, then it would be 3,500.

Answer 2

guitar thats not correct, set it up like 10x + 5y =325000

Answer 3

then X + y = 35000, x being lower level and y being upper

Answer 4

2x + y = 65000, then subtract x + y = 35000 from that to get X = 30000.

Answer 5

then you have y + 30000 = 35000 so y = 5000

30000 lower level tickets were sold and 5000 upper level tickets were sold
