"or"

[edmund@vocalis.com]

Greetings, Lojban people! Can any of you tell me what "chips with cola
or coffee cost one dollar" is in Lojban, and what a literal
back-translation would be?

I was trying to work it out myself from
http://xiron.pc.helsinki.fi/lojftp/reference-grammar/chap14.html

I suppose that logically it's a kind of "and" (".e") because it means
"chips with cola cost one dollar, and chips with coffee cost one
dollar", and "with" corresponds to "joi" ...?

If you've time, another question: how to disambiguate the various
senses of "Suggest to her that she offer the guests ketchup or
mayonaise" where the food choise could be made by the addressee, "her"
or the guests.
