-----------------------------

def select_shops shops, wanted_min, wanted_max
   shops.select do |shop|
     (wanted_max ? wanted_max>= shop[:prices].min : true) &&
     (wanted_min ? wanted_min<= shop[:prices].max : true)
   end
end

shops= [{:name=> 'Company A', :prices=> 1_000.. 3_000},
         {:name=> 'Company B', :prices=> 6_000..10_000},
         {:name=> 'Company C', :prices=>   500.. 2_500}]

select_shops(shops, 2_500, 4_000).each do |shop|
   puts shop[:name]
end
