Perhaps it was supposed to be an overdot https://en.wikipedia.org/wiki/Dot_%28diacritic%29 which is supposed to put a small dot above the x, which typically means a time derivative.

I didn’t consider that it could be an overdot.
Next question:
- Is ‘x’ a function of time or of ‘cost’?
- Is ‘cost’ a constant or a function of time?
