Owen was stacking popcorn balls on a table. He put sixteen balls on the table. He added three more layers. Each layer had four fewer balls than the previous layer. How many popcorn balls in all did Owen put on the table?

4

8
12
16

What is the total?

40 popcorn balls? I am right i think.

Right.

Thanks

You're welcome.

To find the total number of popcorn balls Owen put on the table, we need to calculate the number of balls in each layer and then add them up.

The first layer has 16 balls.
The second layer has 16 - 4 = 12 balls.
The third layer has 12 - 4 = 8 balls.

To calculate the total number of balls, we add the number of balls in each layer:

16 + 12 + 8 = 36

Therefore, Owen put a total of 36 popcorn balls on the table.
