Several public officials who went on the Tall Ships ferry boat party cruise have paid for their share of the cost of the trip, The News & Observer reports today, but it looks like one of them had a little trouble doing the math. The state estimated the cost per person for the cruise was $91.25. Some, like Republican Rep. Bill Daughtridge and Democrat Rep. Russell Tucker, obviously calculated for two and paid $182.50. But Democrat Rep. Margaret Dickson’s calculator apparently failed her: she paid $181.50.
