consider the drug company PharmaTek, which produces a patented drug that treats a rare disease. It sells this drug both to consumers in the US as well as to consumers in the Rest of the World (RoW). The company estimates that demand for their drug in the US and RoW can be given by: PUS = 10.8 0.035QUS PRoW = 7.8 0.015QRoW In these equations P is the price (in dollars) per dose of the drug and Q is the number of doses demanded in millions. Given various laws restricting the import and export of prescription drugs, the company does not have to worry about resale of the drug from the US to the RoW and vice versa. I.e., it can keep the markets totally separate. This drug cost about $1.7 billion to develop, but the cost of producing each individual dose (no matter where it's going) is just $0.30. (You can ignore any other costs not listed here.) (a) (5 pts) At any given price, which market (US or RoW) has more elastic demand
