Note. It often happens in business, that by inverting a queftion; that is, by calling your price the quantity, and the quantity your price; you may find the answer much easier, and fooner than by the common method.

EXAMPLES. What will 29 yards What will 26/6. come to at 61d. come to, at 1s. 6d. or 18 yards at per lb. or 61 lb. at 2s. 2d. ?
