The Demand for sugar in Canada in terms of it's price, P, was once estimated to be QD = 135 - 8P.
If this equation were valid today, calculate the following:
(a) How much would be demanded at P = 10?
b) How much would be demanded if the sugar were free?
c) What price would correspond to QD =95?
d)What is the higest price at which nobody would be willing to pay for sugar?
