Critically evaluate: "In comparing the two equilibrium positions in the diagram below, I note that a smaller amount is actually demanded at a lower price. This refutes the law of demand."A. A decrease in demand from D1 to D2 results in . B. This causes the price to . C. This change in price results in in quantity demanded along the D2 demand curve. D. This change in price results in in quantity supplied. E. The new equilibrium has a and a when compared to the original equilibrium. F. Does this refute the law of demand: . G. Why: (Because the new equilibrium has a lower price and quantity OR Because there was a change in demand).

4. suppose that pollution in a neighborhood comes from two factories, with marginal benefit curves given by mb1 = 12 – p1 and mb2 = 8 – p2. the level of pollution in the neighborhood is given by p = p1 + p2. the government wants to limit pollution by instituting a pollution-rights market. the government’s desired level of p is 10, so it prints 10 pollution rights and offers them for sale to the firms.a)find the equilibrium selling price of a pollution right, as well as the allocation of rights (and hence pollution levels) across the two factories. b)repeat part (a) for the case where the government’s desired level of pollution equals 14. c)comment on the usefulness of a pollution rights market in achieving efficient levels of pollution abatement.

Dr. sperry, a biologist, is using excel to track growth rates of different populations of bacteria. she has a very complex formula in one cell. it begins with “round”. dr. sperry would like to see exactly how excel’s calculation reached the final rounded value that she sees in the cell. what could dr. sperry do to best understand how the calculation was made? try different formulas on her own until she reaches the value shown in excel click on the evaluate formula button in the formulas tab and then click “step in” select the cell and then look at the formula in the formula field of the ribbon remove “round” from the formula in order to see the actual value before rounding
