The total number of pennies Ella has in all is 500.
Disclaimer:
I assume the 50 stickers mentioned in the question as 50 stacks.
Given that Ella has 50 stacks.
And each stack has 10 pennies.
We are asked to find out how many pennies Ella has in all.
The total number of pennies in all is the product of the number of stacks and the number of pennies in each stack.
Let y be the total number of pennies in all.
Then y = 50 * 10
⇒ y = 500.
Refer to the attached image for vertical multiplication.
Therefore, the total number of pennies Ella has in all is 500.
