Hello Bri,
Thanks for your question.
You can view the breakdown of the resources and cost per resource in the cost management and billing section. In Cost Management + Billing, navigate to Cost analysis. You can review the breakdown of your costs.
If you still cannot verify the $29.00 charge and suspect an error, consider contacting Azure Support directly. Use Help + Support > Create a Support Request in the Azure Portal, selecting Billing as the issue type.
