As Scott mentioned, this is probably a better fit use-case for a formula.
I’m not sure what all your pricing ranges need to be, but you can use this formula to get started.
IF(Price <= 5, "$",IF(Price <=10, "$$", IF(Price >10, "$$$")))
If the price is equal to or less than $5, display $
if the price is less than or equal to 10, display $$
if the price is greater than 10, display $$$
It will look like this in your table:
