The demand function of a product is given by p=100-4x, and the supply function is p=1/2x-10. Which of the following is the equilibrium price?
|
11/9 |
|
3 |
|
5 |
|
20/9 |
|
10/9 |
Yanıt Açıklaması:
Writing the demand function for x as x=25-1/4p, and writing the supply as x=2p+20 the equilibrium price may be found as
25-1/4p=2p+20
which is written as
25-20=2p+1/4p
and the price is found as
p=20/9. Therefore, the answer is D.
