Homework Problem Set 4 1. Because Q=12-2P inverse demand P = -0.5 Q+6 For “half price” case‚ P = 2.5‚ Q=7 consumer surplus = 7*(6-2.5)/2 = 12.25 For “buy one‚ get one free” case‚ when original P = 5‚ Q = 4 instead of 2‚ total benefit TB = (4+6)*4/2 = 20 On the other hand‚ payment is 2*5=10 dollars‚ so consumer surplus will be = 10 Thus “half price” gives more surplus. 2. cost minimizing manner‚ marginal product of typewriter/marginal product of word processor=rent of typewriter/rent

Me1 Problem Set #2 The US College Enrollment and the “Third Law of Demand” A theorem proposed by Professors Alchian and Allen in their text‚ University Economics (1964) has had several rebirths of interest in the literature. The so-called “third law of demand‚” or “relative price theorem‚” holds that a fixed cost added to a good of varying quality causes the consumer to prefer the category considered of higher quality to the lower. Recently a number of studies‚ keeping this theorem in mind have

GENERAL BIOCHEMISTRY Problem Set No. 1 Answered by: Andrea Rose A. Fajardo of BSFT 2-1N 1. Calculate the pH of a dilute solution that contains a molar ratio of potassium acetate to acetic acid (pKa=4.76) of: a. 2:1 pH = 4.76 + log[2]/[1] = 4.76 + 0.3010 = 5.06 b. 1:4 pH = 4.76 + log[1]/[4] = 4.76 + (-0.6021) = 4.16 c. 6:5 pH = 4.76 + log[6]/[5] = 4.76 + 0.0792
