Answer:
A. need payoff
Explanation:
Based on the information provided within the question it seems that the salesperson's SPIN technique is an example of a need payoff. This term refers to asking an individual/customer about the value or importance that something can provide them. Which is exactly what the salesperson is stating by asking "how much money (value) can this save you?"
Answer:
P(13,2) = 169
Explanation:
We have to calculate the combinations for left and right shoe considering is not the same having a right shoe blue and left red than having a right shoe rend and a left red.
there are 13 pairs from whcih she will take a single pair:
![P(n,r) = n^{r} \\](https://tex.z-dn.net/?f=P%28n%2Cr%29%20%3D%20n%5E%7Br%7D%20%5C%5C)
where:
n = number of pair = 13
r = shoes = 2 (one on each foot)
![P(n,r) = 13^{2} \\](https://tex.z-dn.net/?f=P%28n%2Cr%29%20%3D%2013%5E%7B2%7D%20%5C%5C)
P(13,2) = 169
Answer:
Part a: The value of Y_A and Y_B are
and
respectively.
Part b: Y_A and Y_B are given as
and
respectively for maximization of Y_B
Part c: The condition for the Pareto efficient allocation is Y_A=Y_B
As the value of Y_A and Y_B are not equal in part 2 thus the condition is not Pareto efficient
Explanation:
Part a
For the value of the utility function is given as
![\bar{u}_A=xY_A\\Y_A=\dfrac{\bar{u}_A}{x}](https://tex.z-dn.net/?f=%5Cbar%7Bu%7D_A%3DxY_A%5C%5CY_A%3D%5Cdfrac%7B%5Cbar%7Bu%7D_A%7D%7Bx%7D)
Also the YB is given as
![Y_A+Y_B=100-x\\Y_B=100-x-Y_A\\Y_B=100-x-\dfrac{\bar{u}_A}{x}](https://tex.z-dn.net/?f=Y_A%2BY_B%3D100-x%5C%5CY_B%3D100-x-Y_A%5C%5CY_B%3D100-x-%5Cdfrac%7B%5Cbar%7Bu%7D_A%7D%7Bx%7D)
So the value of Y_A and Y_B are
and
respectively.
Part b:
Now
![\bar{u}_B=xY_B\\\bar{u}_B=x(100-x-\dfrac{\bar{u}_A}{x})\\\bar{u}_B=100x-x^2-\bar{u}_A](https://tex.z-dn.net/?f=%5Cbar%7Bu%7D_B%3DxY_B%5C%5C%5Cbar%7Bu%7D_B%3Dx%28100-x-%5Cdfrac%7B%5Cbar%7Bu%7D_A%7D%7Bx%7D%29%5C%5C%5Cbar%7Bu%7D_B%3D100x-x%5E2-%5Cbar%7Bu%7D_A)
For the maximization
![\dfrac{\partial \bar{u}_B}{\partial x}=0\\\dfrac{\partial (100x-x^2-\bar{u}_A)}{\partial x}=0\\100-2x=0\\x=100/2\\x=50](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cpartial%20%5Cbar%7Bu%7D_B%7D%7B%5Cpartial%20x%7D%3D0%5C%5C%5Cdfrac%7B%5Cpartial%20%28100x-x%5E2-%5Cbar%7Bu%7D_A%29%7D%7B%5Cpartial%20x%7D%3D0%5C%5C100-2x%3D0%5C%5Cx%3D100%2F2%5C%5Cx%3D50)
From question 1 Y_A and Y_B are given as
and
respectively for maximization of Y_B
Part c:
At the Pareto efficient allocation
![\dfrac{Mu_X}{Mu_{Y_A}}=\dfrac{Mu_X}{Mu_{Y_B}}](https://tex.z-dn.net/?f=%5Cdfrac%7BMu_X%7D%7BMu_%7BY_A%7D%7D%3D%5Cdfrac%7BMu_X%7D%7BMu_%7BY_B%7D%7D)
This is simplified to
![\dfrac{Y_A}{x}=\dfrac{Y_B}{x}\\Y_A=Y_B](https://tex.z-dn.net/?f=%5Cdfrac%7BY_A%7D%7Bx%7D%3D%5Cdfrac%7BY_B%7D%7Bx%7D%5C%5CY_A%3DY_B)
The condition for the Pareto efficient allocation is YA=YB
As the value of YA and YB are not equal in part 2 thus the condition is not Pareto efficient
Answer: A is the answer
