Summed price: I want to display price in two ways -- one as a base value, and one as a multiple by 4

My product shows price as a Entry level and as a Total.
Some products have Total = Entry, while other products are Total > Entry).

e.g.,
Product 1:
Entry = $4000
Total = $16000 ($4000 x 4)

e.g.,
Product 2:
Entry = $4000
Total = $4000 ($4000 x 1).

So I'd like to display these two 'attributes'. One attribute is specified as a fixed price, which is Base. A summed price can then show the total price.

My understanding is that treating Price as a separate attribute means that price utility is estimated discretely; using summed price means that price utility is estimated continuously (which is why the summed price requires some degree of 'shock', like +/- 20%'.

If the % specification for price variation is set to 0%, I'd get a warning.

"You will NOT be able to estimate price sensitivity for your study. The negative utilities for the level-based prices you have specified will be confounded with the preferences for the levels they are associated with."

I get that the lack of variation means that there's no information. I don't really understand the the second sentence concretely. What does it mean exactly?

More practically, is there a way to display the aesthetic of a "Total" price, as in the above examples?

(The other way I considered was just to do two attributes: Base price ($, $$, $$$ levels) and Renewability (renewable, non-renewable). It's just that I didn't want people doing math on the tasks...
