It depends on how much it weights but if it is just first class letter (less than 1 ounce) the rate is 45 cents.
That would depend on the weight of the letter. Postage is 42 cents per ounce, with each additional ounce requiring more postage. Your local post office can weigh it for you. Or if you have postal scales you can weigh it, then call your post office, tell them how much the letter weighs, and get them to tell you how much postage it will need.
