AA. 1. Over time, the costs of processing go down because as organizations learn how to do things better, they become more efficient. In color film processing, for example, the cost of a 3-by-5-inch print fell from 50 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 Foods will soon celebrate its twenty-fifth birthday, we can expect that our long experience will enable us to minimize costs and thus maximize profits

AI  68. “Since the physical work environment affects employee productivity and morale, the employees themselves should have the right to decide how their workplace is designed.”

Math: 寫些JJ上沒有的

1. 兩點(-1.3), (2,-1)在座標平面上，若這兩點的距離是一個正方形的對角線長且這兩點是對角線上最遠的點(the end point)，求此正方形的周長為多少?

   Ans: 兩點距離為5，正方形邊長為 (5*根號2)/2，周長為10*根號2

2. DS: 求 X^2-Y^2/X-Y=?

   (1) X^2-Y^2=16

   (2) X+Y=9

   Ans : B

3. (不好意思不會畫圖，大家將就著看) 給你一個數軸，數軸上有刻度，題目說這些刻度都相同，上面有依序有C，X，D三點。C與D之間有五個刻度，X比C多一個刻度，how to determine X in terms of C and  D?

  Ans: 4C+D/5  (這題我差點被騙了，選項有D-C/5，但是因為X比C多一個刻度，所以要再加C才能表示X的值，大家要小心! )

4. DS  P與N都是整數，求P到N之間有多少個整數?

   (1) P=7

   (2) P=N+10

   Ans: B

Verbal:

閱讀:有三篇是JJ (GWD勞動力，黑奴，慢波睡眠)

這個月的機經很豐富，大家看JJ就夠了。因為我verbal不高，就不誤導大家了。

謝謝這個月貢獻JJ還有辛苦整理JJ的版友們，希望大家都有個滿意的成績。

Thanks
