A company produces a certain item whose demand function is p=-4x+150, and supply function is p=6x-275. For what values of x is there a market shortage?


x>42,5

x<42,5

x<21

x>21

x<47,5


Yanıt Açıklaması:

We first find the equilibrium point by equating the supply and demand functions. Therefore, the equality 

-4x+150=6x-275, x=42,5. Because there will be a shortage in the market, to the left of this point the correct is x<42,5. Therefore, the answer is B.
