Which data model has the highest level of abstraction?

Afirm that makes electronic circuits has been ordering a certain raw material 250 ounces at a time. the firm estimates that carrying cost is i = 30% per year, and that ordering cost is about $20 per order. the current price of the ingredient is $200 per ounce. the assumptions of the basic eoq model are thought to apply. for what value of annual demand is their action optimal?

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.

The struter partnership has total partners’ equity of $510,000, which is made up of main, capital, $400,000, and frist, capital, $110,000. the partners share net income and loss in a ratio of 80% to main and 20% to frist. on november 1, adison is admitted to the partnership and given a 15% interest in equity and a 15% share in any income and loss. prepare journal entries to record the admission of adison for a 15% interest in the equity and a 15% share in any income and loss under the following independent assumptions. (1) record the admission of adison with an investment of $90,000 for a 15% interest in the equity and a 15% share in any income and loss. (2) record the admission of adison with an investment of $120,000 for a 15% interest in the equity and a 15% share in any income and loss. (3) record the admission of adison with an investment of $80,000 for a 15% interest in the equity and a 15% share in any income and loss.
