Power BI Embedded A1 SKU Billing

Hi,

I am a bit new to Azure SKU hourly pricing ... have a basic question.

Say i were to use Azure A1 SKU for Power BI Embedded and create 5 reports/dashboards that are embedded into my application and available for the entire month. Suppose these reports are opened (queried) only for few random days (say once a week) by say 10 of my customer's users. Then, how would the billing work?

A) Will I be charged $750 (for A1 SKU) for having the dashboards hosted and available for the entire month?
B) Will I be charged only for the time the dashboards are opened/called which could be only a few minutes a day (or a total of just few hours for the entire month)?

If there is anything more to know/understand this, would appreciate more details? Thank you
