Use the following general linear demand relation:Qd = 100 - 5P +0.004M - 5PRwhere P is the price of good X, M is income, and PR is the price of a related good, R. Income is $80,000, and the price of the related good is $40. Also let consumers' tastes change so that consumers now demand 100 more units at each price. When the price of the good is $50, how many units of the good are demanded?
