 In this example, one Namespace consumed 100 million Actions in a calendar month and one consumed 500 million Actions during the same month.
 Here's how the billing works for these two Namespaces and across tiers:
 
-- The first Namespace using 100 million Actions is billed at the $23.25 per million Actions tier, a $2,325 invoice line item.
+- The first Namespace using 100 million Actions is billed entirely at the $23.25 per million Actions tier:
 
   ```
   100M Actions ⨉ $23.25 per million Actions = $2,325 (Namespace total)
   ```
 
-- The second Namespace with 500 million Actions is billed as follows:
-  - The first 300 million Actions are billed at the $23.25 Actions tier.

-    ```
-    300M Actions ⨉ $23.25 per million Actions = $6,975

-  - The remaining 200 million Actions are billed at the $18.80 per million Actions tier.
