Suppose a grocery store's sales are 200,000 TL in one year. During this same time period, the firm paid 50,000 TL for grocery stock sold, 70,000 TL for wages and salaries, 20,000 TL on taxes and insurance, and 10,000 TL on other expenses. At the beginning of this period, the grocery store owner had received the following two offers:He could rent the store to another grocer and work for a large chain in which case he wouldmake a return of 35 ,OOO TL during that year (including his salary).Offer II: He could have sold the store and invested in a stock which together would have yielded a returnof 35,000 TL during that year, and gotten a job paying 15,000 TL.
He declined both offers.
a.What is the difference between explicit and implicit costs to a firm? What is the implicit cost of the businessin question?b.Calculate his economic profits for the year.c.Was his decision to keep the grocery store economically rational? Explain why or why not. By referring tothe relevant concepts.

Imagine Tom's annual salary as an assistant store manager is $30,000, he owns a building that rents for $10,000 yearly, and his financial assets generate $1,000 per year in interest. One day, after deciding to be his own boss, he quits his job, evicts his tenants, and uses his financial assets to establish a bicycle repair shop. To run the business, he outlays $15,000 in cash to cover all the costs involved with running the business, and earns revenues of $50,000. Which of the following statements is true?
Tom earns an accounting profit of $35,000.
Tom has an opportunity cost of $41,000.
All of these are true.
Tom experiences an economic loss of $6000.

You consider borrowing this amount to buy the building, use it for one year, and then sell the building to pay back the loan. Unfortunately, the economy in which you are operating is experiencing deflation at the rate of 10% per year. After one year, you should be able to sell the building for___________. Suppose that owning the building for a year would earn you $12,000. To decide whether you will be better off by owning it for one year and then selling it, you seek advice from three different people: (1) Your brother says that you should not buy the building because in one year it will cost you $200,000. (2) Your accountant says that you should definitely buy the building because you can borrow $200,000 at zero interest while the building will generate $12,000 in extra income. Then when you sell it, you will be $12,000 richer. (3) Your…arrow_forwardcompute the marginal product of capital (MPK) and the marginal product of capital (MPL) of b. Q=K2/ 5L3 /5arrow_forward
