Q-mart failed to include inventory that was kept in a separate warehouse in its 12/31 end-of-the-period inventory count. Consequently, the ending inventory on 12/31 was understated on the balance sheet. Explain how this error will effect the current year's income statement. (Check all that apply.)

White truffles are a very prized and rare edible fungus that grow naturally in the countryside near alba, italy. suppose that it costs $200 per day to search for white truffles. on an average day, the total number of white truffles (t) found in alba is t = 20x − x 2 , where x is the number of people searching for white truffles on that day. white truffles can be sold for $100 each. if there is no regulation, how many more people will be searching for white truffles than the socially optimal number?
