     Note that the interpolation expression `item.Price` in the interpolated string resolves to the text "1.99" in the result string. That's because, when the type of the expression result is not a string, the result is resolved to a string in the following way:

     In the previous step, two poorly formatted strings were inserted into the result string. One was a date and time value for which only the date was appropriate. The second was a price that didn't indicate its unit of currency. Both issues are easy to address. String interpolation lets you specify *format strings* that control the formatting of particular types. Modify the call to `Console.WriteLine` from the previous example to include the format strings for the date and price expressions as shown in the following line:
 
     ```csharp
-    Console.WriteLine($"On {date:d}, the price of {item.Name} was {item.Price} per {item.perPackage} items");
+    Console.WriteLine($"On {date:d}, the price of {item.Name} was {item.Price:C2} per {item.perPackage} items");
     ```
 
     You specify a format string by following the interpolation expression with a colon (":") and the format string. "d" is a [standard date and time format string](../../../standard/base-types/standard-date-and-time-format-strings.md#the-short-date-d-format-specifier) that represents the short date format. "C2" is a [standard numeric format string](../../../standard/base-types/standard-numeric-format-strings.md#the-currency-c-format-specifier) that represents a number as a currency value with two digits after the decimal point.
