8. The head of the hospital’s accounting department is concerned about the prescribed charge for services versus the actual charges for services in the surgery category of services (service_cat_id = ‘SUR’). Produce a listing of surgery services listed in the treatment table by service_id where the prescribed service_charge differs from the actual_charge recorded in the treatment table. The result table should also include the service_charge and actual-charge. Use a subquery approach to produce a listing of service_id values from the service table that belong to the ‘SUR’ category of services. Display the result table with the service and actual charges formatted to include the dollar sign ($)

In anticipation of a change to the database, you are asked to provide a list of all products that have 'Man-Made' or 'Man Made' in the the composition text. (HInt: It is easiest to use LIKE in this instance.) In addition, you are requested to replace either 'Man-Made' or 'Man Made' with the word 'Synthetic'. Only include ProductIDs between 1050 and 1060. Show the following in your answer: ProductID, ProductName, Composition, and the modified composition field as 'NewComposition'.
