There were 240 adult tickets sold and 380 student tickets sold.
Step-by-step explanation:
How did I get this?
First, I divided 620 by 2. You get 310. Then I subtract 70 by on of the 310's. You get 240. I take that 70 that I subtracted and add it to the other 310, you get 380. (This may sound confusing so I will write it out)
