Enter a SQL SELECT command that displays the following from the Sales.SalesTerritory table: TerritoryID, Name, SalesYTD, SalesLastYear, and a formula that calculates the percent change in sales. The formula for percent change should divide the difference between SalesYTD and SalesLastYear by SalesLastYear and multiply by $100.$ Assign an appropriate column heading such as PercentChange to this formula. Include a clause that will limit results to rows where the CountryRegionCode is $\text{'}$US$\text{'}.$
