Assume that Bob's utility function over beer x and pizza y is U(x,y) = 4x+12y. Which of the following statements is false? If the price of pizza is 15 and the price of beer is 5, the own price elasticity of the demand for pizza as well as beer is infinite. It the price of pizza is 15 and the price of beer is 4, Bob purchases only beer If the price of pizza is 16 and the price of beer is 5, then Bob only purchases pizza. If the price of pizza is 12 and the price of beer is 4, then we can't determine how much pizza relative to beer Bob purchases. Pizza and beer are perfect substitutes.
