1.500000/10=50000
2.P=-0.4*10%=-4%,销量n=50000*（1-4%）=48000
3.M=48000*（1+10%）*10=528000
4.旧利润=500000-4*50000-100000=200000
新利润=528000-（48000*4+100000）=236000,利润增长率=36000/200000=18%

这是英语题吧……

1.x^2+kx-2的一个根是1，则它的另一个根是多少？ x^2+kx-2=0的话，把x=1代入，求出k=1,所以：x^2+x-2=0求出另一个根：x=-2 2.kx

看不懂

fullfill the answer of question 9:
We can choose the 3 distinct flavors out of the available 5 in C(5,3) = 5! / ( 3! (5-3)! ) = 10 ways.
For each such choice, we can choose one of the two available cones in C(2,1) = 2 ways.
So the number of possible flavor-triplet-cone combinations is C(5,3)*C(2,1)= 20.
