By circa 1990, I believe the course was called Life Skills or something of that ilk, and was not mandatory. (I didn’t take it, although it would have been one hell of a lot more useful than PhysEd, I’m sure.) We did cover some related material in math classes at various points.

Really, you coulld put this in elementary schools—none of it needs more than fourth-grade math. Basic arithmetic operations, percentages, decimal points.
