Gaining inequality 2000
Get 2000
Get 22 1.2.
Must be an integer, then X=222,
Then nine consecutive odd numbers are 2 15, 2 17, 2 19, 22 1, 223, 225, 227, 229, 23 1.
2. Set the price of X yuan, and add up the ***T terms to get the inequality.
0.8T & lt=X( 1-5%)T
Get X & gt=0.842.
So the price is at least 0.85 yuan.
3. The original total output value was 100A, and now the total output value of production personnel is (100-x)1.2a..
The inequality of the total output value of service personnel is 3.5AX.
( 100-X) 1.2A & gt; = 100A,x < = 16.7
3.5AX & gt=0.5* 100A,x >; = 14.3
On the whole, X= 15 or 16.
The number of service personnel is 15 or 16.
