You now know that demand equations can be estimated using regression methodology.Suppose that you collect data and run a regression to estimate the demand equation for a particular product.The resulting demand equation is as follows:

Q_D=6000-2P_X-0.2I+4P_Y-2P_Z

Were

Q_D= quantity demanded of good X

P_X= price of good X

I= consumer income,in thousands

P_Y= price of good Y

P_Z= price of good Z

If the price of good X is $100, what is the quantity demanded?
