Adult tickets to a concert sold at $8, while student tickets cost $5. If 70 tickets were sold for a total of $440, how many adult tickets were sold?

40 tickets

30 tickets

55 tickets

15 tickets

30 tickets

Step by step:
When you multiply 30x8 you get 240. You multiply by 8 because that is how much one adult ticket costs. And they tell you that they sold a total of 70 tickets, which means to find the number of children tickets that were sold would be 70-30=40. Then to prove that for sure, multiply...

40x5=200. You multiply by 5 because that is how much one children ticket costs.

Then when you add the totals of the adult tickets sold and the children tickets sold, you get $440, which means that 30 adult tickets were sold!!

You can use this same process for problems like these or to verify the answer!
