How much per pound does it cost to transport Trump?

I estimated that Trump weighs 300 pounds. And now i want to start figuring out how much it costs to transport that 300 pounds to some of the places he travels to on the tax payers dime. And if the tax payers got their moneys worth. Trump just made a trip to Ireland - it probably cost a fortune to get him and his stuff there. He spent under 5 minutes talking in private with Irelands president - so I can't see how American tax payers got their 300 pounds worth on that one. Cheers!
