Creating objects of the currency class requires a name (string ), a currency symbol (string ) and the number of decimal places (integer ) usually associated with the currency (in that order). define an object named curr, of type currency corresponding to "us dollar" with the symbol "$" and 2 decimal places.

We are given with
name = curr
currency = $
decimal places = 2

Defining the object requires declaring it as a string character. So,
string.Format("$", "{0:0.00}")

The object is string with keyword string
The format is that there is a dollar sign at the start and a number of two decimal places hence the format 0:0.00

I'm thinking it's the egg beater.
