reasoning and show any calculations. c. If Jane is not maximizing her utility with the original purchase combination, remembering the Law of Diminishing Marginal Utility, would she be better off buying just one more fry? Explain your reasoning and show any calculations. d. If Jane is not maximizing her utility with the original purchase, remembering the Law of Diminishing Marginal Utility, would she be better off buying one less fries and one more chicken sandwich? Explain your reasoning and show any calculations. 2. Remembering the Learning Practice in Unit 3, in the year 107 WBCE (Way Before the Common Era) the Gondwanaland Chairman of Production reported that the gosum berry growers were able to meet an average demand of 700 barrels of gosum berries per month at an average a price of \$70 per barrel. In the year 108 WBCE the growers were plagued with a gosum berry bug infestation that reduced average output, causing production to fall to only 600 barrels per month, causing the price to rise to \$84 per barrel. The following table shows the Chairman’s report: Year (WBCE) Monthly barrels of gosum berries demanded Price per barrel 107 700 \$70 108 600 \$84 a. Using the midpoint method, calculate the price elasticity of demand for Gondwanaland gosum berries. Explain what this price elasticity of demand means? % change in quantity demanded: = - 100 / (700 + 600)/ 2 = 100/650 = 0.1538461538461538 = 15.38% % change in price: = 14 / (70+84)/2 = 14/77 = 0.1818181818181818 v.6.16.17 3 of 5

Unit 4 AB224 | Microeconomics = 18% Midpoint method: 15.38/ 18= 0.8462 = .85 b. What is the monthly average total revenue for year 107, and the monthly average total revenue for year 108? How do these numbers compare to each other? Year (WBCE) Monthly barrels of gosum berries demanded Price per barrel Monthly average total revenue 107 700 \$70 \$49000 (700x70) 108 600 \$84 \$50400 (600x84) Change in average total monthly revenue \$-1400 c. Using your answer to part a. above, how could you have predicted this change in total monthly revenue? 3. The Gondwanaland Chairman of Production reported that the new Altair chariots (most modern, horse drawn family chariot) had a PRICE elasticity of 3 and an INCOME elasticity of 2. The supply of these Altair chariots is elastic. Evaluate the following statements and explain why you think they

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
