终于做对了..nice

So much as是对的
As when 排除C
平行结构，排除DB

请问D选项为什么最后是is不是are？

这些题目感觉大部分是做过的。

thx

把条件二想成积是30了，啊啊啊啊

我艹......分子分母都要减Y

为什么c选as much as放后面就不能修饰hours

1）通过电脑和打印机的倍数关系确定二者大小关系，电脑C最多是打印机P的3倍，也就是C ≤ 3P
The number of computers can be at most 3 times the number of printers
Let C = the number of computers purchased
Let P = the number of printers purchased
So, we can write: C ≤ 3P
Subtract 3P from both sides of the inequality to get: C - 3P ≤ 0

2）买电脑和打印机一起的钱z最多不超过是$9100
Computers cost $1,500 each, and printers cost $300 each.
So, the total cost of purchasing C computers and P printers = 1500C + 300P

What is the greatest number of computers can the company buy if it has a total of $9,100 to spend on computers and printers?
This tells us that the total cost cannot exceed $9100
So, we can write, 1500C + 300P ≤ 9100

3）联立不等式，求得C的范围
We now have the following system of inequalities:
C - 3P ≤ 0
1500C + 300P ≤ 9100

Take the top inequality and multiply both sides by 100 to get:
100C - 300P ≤ 0
1500C + 300P ≤ 9100

Since the inequality symbols are facing the same direction, we can add the two inequalities to get: 1600C ≤ 9100
Divide both sides of the inequality by 1600 to get: C ≤ 9100/1600
Simplify to get: C ≤ 5.something

C最大是5

T=40/60=2/3
T1=20/50=2/5
T2=2/3-2/5=4/15
S2=20/(4/150)=75

看不懂为啥是转折关系，既然11月份好卖，卖的更好不是更好解释么

and the time required for a stroke is exactly equal to the time interval between strokes
敲钟和间隔时间一样
敲6次+间隔5次 = 11
22/6 = 2
12+11 = 23
23*2 =46

假设总收入是x

【文字解读有问题】for any week is $360 plus 6 percent of the portion of A's total sales above $1,000 for that week.
翻译：360 + 6% of the 总收入x超过1,000的部分

which will be
360+6%(x-1,000) = 8%x
x = 15,000

因为公约数不能大于两数

这题不给条件也推的出？

3P+1>10且2P<10，P可以取3、4。
有3P+1=S+10：
P=3时，S=0；P=4时，S=3。

方案模式
为了吸引住民，建造公共设施

削弱，削弱方案可行性/可操作性，说明否定性副作用

A、developers将建设设施的花费转化为高房价，把住民推得更远了，付不起房价，方案可行性弱；有力的削弱，CORRECT

B、轻工业带来更多就业机会，无关
C、其他城镇也着手做类似的事情吸引住民（说明它是可行的），增强
D、developers将建造公共设施的成本早就算进总成本里了（意译），具有可操作性，增强
E、一些新买房的人将recreational列为买房重要影响因子，可行性强，增强

需要多嘗試幾個梯隊，不能一看到25*2 + 10 *1 + 5 = 能湊出最小的數字65就完成
需要嘗試25盡可能多

主要題目沒理解清楚

記得要+1
因為 35, 85都是odd, 所以需要+1
