In the year following an eight-cent increase in the federal tax on pa pack of cigarettes, sales of cigarettes fell ten percent. In contrast, in the year prior to the tax increase, sales had fallen one percent . The volume of cigarette sales is therefore strongly related to the after-tax price of pack of cigarettes. 问Assumption: 答案For the year following the tax increase, the pretax price of a pack of cigerattes was not eight or more cents lower than it had been the previous year. 能翻译并分析一下吗? |
