Expert Solution

Question:

(a) the demand function for SSC is given by:

QD = 10000 - 25P

At Price = 100, we have, QD = 10000 - 25*100 = 7500

(b) QD = 0 => 10000 - 25P = 0

=> P = 10000/25 = 400

MR = dTR/dQ = 400 - 2Q/25

(d) price elasticity of demand = (change in quantity demanded / change in price)*(original price/ original quantitiy)

= (-25)*(150 / 6250)

= -0.6

Total revenue = 150*6250 = 937500

Marginal revenue = 400 - 2*6250/25 = -100

(e)

price elasticity of demand = (chnage in quantity demanded / change in price)*(initial price/ initial quantitiy)

= (-25)*(250 / 3750)

= -1.66

Total revenue = 250*3750= 937500

Marginal revenue = 400 - 2*3750/25 = 100

(f) at price = 300, QD = 10000 - 7500 = 2500

QS = -5000 + 50*300 = 10000

Thus, quantitiy supplied = 4*quantitiy demanded

(g) Equilibrium inthe market occurs when demand = supply and the price is same. Thus,

=> 10000 - 25P = -5000 + 50P

=> 75P = 15000

=> P = 200

=> Q = 10000 - 25*200 = 5000
