:point_right: A string literal is simply anything that is enclosed in quotes.

It can be any combination of words, letters, spaces, and symbols. In this case, the challenge asks you to use string interpolation which means that your string literal will include special combinations of certain symbols and variable names which will then be substituted by values from your program.

You might want to re-watch the appropriate video if you're not sure how to indicate substituted values for interpolation.
