机经：AA：44、The following is part of a business plan created by the management of the Megamart grocery store. “Our total sales have increased this year by 20 percent since we added a pharmacy section to our grocery store. Clearly, the customer’s main concern is the convenience afforded by one-stop shopping. The surest way to increase our profits over the next couple of years, therefore, is to add a clothing department along with an automotive supplies and repair shop. We should also plan to continue adding new departments and services, such as a restaurant and a garden shop, in subsequent years. Being the only store in the area that offers such a range of services will give us a competitive advantage over other local stores.” AI是这篇：115.Technology ultimately saparates and alienates people more than it serves to bring them together.

我的数学里也有此题：摘自yeahy的机经： 买第一双鞋原价，再买第二双可在原价上打5折，前提是第二双的原价不超过第一双。若第二双原价为第一双的XX%（这里有个具体数的，但不记得了），问总共两双鞋打了几折
还有老机经里的那道：有9600个商品A,COST是$1.25,现这样出售，把3/4的商品按$2。5出售，其余的按$1.5出售，问获利多少？ 选项中最大的才$1600。也不知我是哪儿被绕住了？？？ 感谢jetrong补充题目：第9题我在3月4日考试中碰到! 要特别注意单位，因为$1.25是一打的价格，所以答案还要除以12 !(去年三月JJ)(重复两次) 橙子评价：按题目条件，求出获利是［9600*(3/4)*(2.5-1.25)+9600*(1/4)*(1.5-1.25)］／１２=８００
