This weekend, Martha has time to read 40 pages of economics and 30 pages of marketing books. Alternatively, she could read 10 pages of economics book and 90 pages of marketing book. Which of these equations describes all combinations of pages of economics, E, and marketing, M, that she could read over the weekend? Please show your work.
a. E/2 + M = 50.
b. E + M = 100.
c. E + M = 70.
d. 2E + M = 110.
2. Jane has indifference curves that have two goods with the equation X2 = constant - 4(X1)^(1/2), where larger constants correspond to higher indifference curves. If X1 (good 1) is drawn on the horizontal axis and X2 (good 2) on the vertical axis, what is the slope of Jane’s indifference curve when her consumption bundle is (36, 10)?
