I wouldn't say that templates are "for" functions. It's more like they are "for" the combination of arguments to the function, which in this case is the structure, because functions on the structure will all share the same template. Furthermore, you can't write the template for a structure unless you know what kind of values the fields contain, which your excerpt doesn't contain. Plus, I don't think I should do your homework. I could post an example, but the HtDP 2e link I referenced before has a ton with more explanation than I would copy in to this email.
