200 X 3 = 600 tickets total need to be sold
600-206-185 = 209 tickets need to be sold the third night
Answer:209
Step-by-step explanation:
Given
200 tickets needed to be sell per night to make a profit.
For first two nights 206 and 185 tickets were sold
Let x be the tickets sold on third day
therefore their average must be equal to 200
[tex]\frac{206+185+x}{3}=200[/tex]
600=206+185+x
x=209
Therefore tickets sold in third day is 209
