The following appeared as partof an annual report sent to stockholders by Olympic Foods, a processor offrozen foods.
“Over time, the costs of processing go down because asorganizations learn how to do things better, they become more efficient. Incolor film processing, for example, the cost of a 3-by-5-inch print fell from50 cents for five-day service in 1970 to 20 cents for one-day service in 1984.The same principle applies to the processing of food. And since Olympic Foodswill soon celebrate its twenty-fifth birthday, we can expect that our longexperience will enable us to minimize costs and thus maximize profits.”

1. To beeligible for retirement benefits at the Omega Corporation, the sum of anemployee’s age, in years, and the number of years of employment must be atleast 89. If x, where x < 89, is a certain employee’s age when hired andy is the minimum number of years of employment required for the employee to beeligible for retirement benefits, which of the following equations representsthe relationship between x and y ?
3. 有一个折线图:是一个什么东西的变化的%,三条线P1, P2, P3。问:哪些是正增长的?选P1andP2, but not P3 (P1和P2所有点都在x轴上方,P3所有点都在x轴下方)P1和哪个成正比例?选P3 (P1和P3虽然一个在x上方一个在x轴下方,但是趋势是一致的,P2跟他们是反比例关系)。
4. 还有一个要看的很仔细的图表。说是一个什么地方在1996年和2000年对1000个当地居民进行survey,问他们哪些服务是essential to their daily life的(有电视啊,洗衣啊,等等那些),1996年有10个服务,2000年加了两个变成12个服务。表格里的数字就是选这个服务是essential的人数(0-1000之间,1996年survey里没有那两个服务显示的是n/a)。选描述正确选yes,描述错误选no. 第一个和第一个问选yes,第三个我忘记了(好像也是yes)。第一问:Exactly half of all theservices in 1996 survey are considered not essential for majority of theresidences. 刚一开始我没仔细看题信息,看到两个n/a,这题就选了no。后来又仔细看了一下题干。发现majority的意思就是大于500人选这个服务的意思!太隐晦了。所以其实就是找在1996那一列小于500的数字是不是刚好和大于500的数字一样多!一看刚好5个对5个。问的二个问题都是majority或者minority之类的,其实都是看在那一列大于500的数字和小于500的数字的多少或者比例关系。第三个问题是说除了那两个2000年有1996年没有的服务,是不是只有一个服务认为essential的人数减少了?就是看1996那一列的数字和2000那一列的数字的大小。
