There were 15 red apples and 6 green apples in a bowl,
Eric ate 2 of the apples,
How many apples are
in the bowl now?

19 apples are left in the bowl

Okay so there are 8 employees and 200 calls per hour for all in 8 hours then all you need to do is multiply the 200 calls per hour by the 8 employees
200 divided by 8 is 25 and 25  times 8 is 200 so each employee makes 200 calls in their work day 
i really hope i helped you out in some type of way :)))
