Now, said he, if I can make 5 per cent. in adyance on their present valuation, clear of all expenses, I shall be satisfied. The question, then, is, at what price he must mark each article, commencing with the first on the inventory, so as to clear the 5 per cent. The pupil will find, by calculation, that the expenses amount to cent. on the actual cost of all the articles; this, added to the 5 per cent., makes 15 per cent, advance ; that is, each article must be marked 15 per cent. highet than its present valuation in the inventory. The answer to each follows in the same order as the articles stand in the above inventory, commencing with the 3 bbls. of sugar, and finding the selling price of each per ib., &c. Note.
