Q. On Friday night 2,950 people attended the rodeo, and 3,159 people attended on Saturday night. If the staudim seats 4,000 people, how many empty seats were there for two nights?

-
A. So do I add 3,159 + 2,950 = 6,109 and subtract 6,109 - 4,000 = 1,891?

There were a total of 8000 seats for the two nights. The empties are therefore

8000-6109=1891

you got the right answer, but 6109-4000 is not 1891.

Wait so 8,000 is the answer or 1,891?

Yes, you are on the right track. To find the number of empty seats, you first need to add the number of people who attended on Friday night (2,950) and the number of people who attended on Saturday night (3,159). So, 2,950 + 3,159 = 6,109.

Then, to find the number of empty seats, you subtract the total number of attendees (6,109) from the total seating capacity of the stadium (4,000). So, 6,109 - 4,000 = 2,109.

Therefore, there were 2,109 empty seats for two nights.
