A producer of fixed proportion goods X and Y (Q = Qx = Qy) has marginal costs and revenues of MC = 10 Q, MRX = 150 - 6 QX, MRy = 30 - 4 Qy. The producer should produce how many units? a. Qx =9, Qy=9
b. Qx = 9, Qy = 7.5
c. Qx = 10, Qy = 10
d. Qx = 9, Qy=0

a. Qx =9, Qy=9

Explanation:

As per the given data

Q = QX = QY

MRX = 150 - 6QX = 150 - 6Q

MRY = 30 - 4QY = 30 - 4Q

MC = 10Q

Now calculate the Marginal revenue as follow

MR = MRX + MRY

MR = 150 - 6Q + 30 - 4Q

MR = 150 + 30 - 6Q - 4Q

MR = 180 - 10Q

The Equilibrium of the producer will be

MR = MC

180 - 10Q = 10Q

180 = 10Q + 10Q

180 = 20Q

Q = 180 / 20

Q = 9

As we know

Q = Qx = QY

Hence, the value of Qx  and QY is 9

i believe it’s b because the rest don’t make sense

answer: a. the kind of population living in your neighbourhood.

the census explorer data tool by the us census bureau allows the user to zoom in on any neighbourhood within the united states and find the kind of people residing in that by race and age.  

the tool needs to needs to be used twice – once in order to find what type of people reside in a neighbourhood, and then to see the age groups of the people in the same neighbourhood.
