Quantity demanded is 200 units when the unit price is set at $90. The quantity demanded is 1200 units when the unit price is $40. Find the demand equation

Step-by-step explanation:

From the question we are told that:

Initial Quantity demanded Q_1= 200 units

Initial demand price

Final Quantity demanded

Final demand price

Generally the  Demand Equation is mathematically given by

Where

a=Other factors affecting price

b=Slope of the demand curve

Therefore

Comparing both above equations

Therefore the  Demand Equation is mathematically given by

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

the answer is stop cheating on things stoopid
