Suppose the demand function for coffee is given by q=200−10pc+20pt−10pm+0.1Y, where pC is the price of coffee, pt is the price of tea, pm is the price of milk, and Y is income. We would like to answer the following question via multiple subquestions: If pC=$5,pt=$2,pm =$2, and Y=$1000, how much would the price of coffee need to rise for the quantity demanded to fall to 250 units? (a) Given the information, demand function is q=[a1]−[a2]pC (b) At pC=5,q=[b] (c) The price of coffee for 250 units to be demanded is pC= [c].
