TUTORIAL1 WITH INFORMATION TO SOLUTIONS 1. For most products‚ higher prices result in a decreased demand‚ whereas lower prices result in an increased demand. Let d = annual demand for a product in units p = price per unit Assume that firm accepts the following price-demand relationship as being realistic: d = 800 – 10p where p must be between $ 20 and $70. a. How many units can the firm sell at the $ 20 per-unit price? At the $ 70 per-unit price?

CAT 2007 Solutions Section I 1. Note that the price of Darjeeling tea remains constant after the 100th day (n=100). If the prices of the two varieties of tea become equal before n = 100‚ then 100 + 0.1n = 89 + 0.15n ∴ n = 220‚ which is not possible. (Since n has been assumed to be less than 100) ∴ The prices of the two varieties will be equal after n = 100‚ i.e.‚ when the price of Darjeeling tea = 100 + 0.1 × 100 = 110 ∴ 89 + 0.15n = 110 ∴ n = 140 2007 is not a leap year.

BUFFERS By: Luis P. Bazan‚ RPh.‚ Ph.D. A buffer solution is a solution of: 1. A weak acid or a weak base and 2. The salt of the weak acid or weak base Both must be present! A buffer solution has the ability to resist changes in pH upon the addition of small amounts of either acid or base. Consider an equal molar mixture of CH3COOH and CH3COONa CH3COOH (aq) H+ (aq) + CH3COO- (aq) Adding more acid creates a shift left IF enough acetate ions are present 16.3 Which of the

05.05 Mixtures and Solutions Background: Paper chromatography is one method for testing the purity of compounds and identifying substances. Paper chromatography is a useful technique because it is relatively quick and requires small quantities of material. Safety: Warnings: * Rubbing alcohol (or isopropyl alcohol) is flammable‚ so be sure to keep it away from high heat or heat sources. * Keep pigments and solutions away from your eyes‚ wash your hands carefully after coming in contact
