Methods should have one purpose. This one tells us if something is possible - true/false. That said, it will look something like:
budgets_list.inject(0, :+) < gift_price

Changing not_possible? method will require some refactoring here as well:
if not_possible?
puts 'IMPOSSIBLE'
return
end

Would be good to collect the results in an array and print it in a print method or in the bottom of the file when you start the script.

Use map and collect the result, so that it is returned from calling start and you'll avoid printing in the middle of an object's method.

Use << operator where suitable, because it's faster. Doesn't create extra string objects.

You may have the same result with:
result ? " #{result[0]} #{result[1]}" : ' -1 -1'Also this methods doesn't actually add any coordinates, it just returns them -> def coordinates(result)
Put print action out of the class and use each_with_object to fill array with contributions
