A& CD Questions 16-20 di Born in England in 1643 to a widowed mother, Isaac Newton was a sickly baby who was not expected to survive for more than a few days. That he lived for 84 years is rural property. (16). Yet, he endured a traumatic childhood. When his mother remarried, he was sent to live with relatives, and (17) without either of his parents turned young Isaac into an anxious and occasionally violent man. Newton also spent a period of time managing his family's 1 (18) this, he suffered from an interrupted education and graduated from the most respected and renowned scientists in history. Throughout his career, he made university later than his peers. Despite all these (19), Newton went on to become one of numerous discoveries in fields ranging from mathematics to optics. However, it is his three laws of motion (20). Indeed, they still form the basis of modern physics today. eletexibil sivom brs monqoq ro 非凡的 16. A remarkable Dia ebialuo (ET) 17.

7. In 2010, Americans smoked 315 billion cigarettes, or 15.75 billion packs of cigarettes. The average retail price (including taxes) was about $5.00 per pack. Statistical studies have shown that the price elasticity of demand is -0.4, and the price elasticity of supply is 0.5. a. Using this information, derive linear demand and supply curves for the cigarette market. b. In 1998, Americans smoked 23.5 billion packs cigarettes, and the retail price was about $2.00 per pack. The decline in cigarette consumption from 1998 to 2010 was due in part to greater public awareness of the health hazards from smoking, but was also due in part to the increase in price. Suppose that the entire decline was due to the increase in price. What could you deduce from that about the price elasticity of demand?
