Getting total sales which has Beverages in it

Hi All,

I am a bit stuck in getting a particular scenario for Tableau so I tried Microsoft SQL server query but not sure how to do it.

I am trying to get total sales for a particular sales order which includes only beverages.

Example: Salesorder1: Beverages - 5$

                                      Chicken - 10$

Salesorder2: Chicken - 12$

                     Chips - 8$

I just need sum of total which has beverages in it. So, as per above examples, I should get (Beverages + Chicken = 15$) and it should not include the salesorder2. 

How can I achieve this in query?
