They purchased 3 tickets for tier seats.

Step-by-step explanation:

From the information given, you can write the following equations:

x+y=12 (1)

45x+60y=585 (2), where

x is the number of tickets for floor seats

y is the number of tickets for tier seats

First, you can solve for x in (1):

x=12-y (3)

Next, you can replace (3) in (2):

45(12-y)+60y=585

540-45y+60y=585

15y=585-540

15y=45

y=45/15

y=3

Now, you can replace the value of y in (3) to find x:

x=12-3

x=9

According to this, the answer is that they purchased 3 tickets for tier seats.
