How much? E.g. in early 1992 monthly stipend of a student - something which he could somehow survive for a month (not quite, too low, but somewhat close) was about 60 roubles. And the USD-RUR course was 100 roubles for a dollar. So a person was barely - very barely - surviving on 7 dollars 20 cents a year.

Do you know how much Russian economy costed at the time?
