Assume that a consumer's utility function is B u(x1, x2) = xxx for some a > 0, B > 0. The initial price of the first good (x1) is P1. Suppose that the price of the first good increases by 50% while the price of the second good and the consumer's income remain the same. How will the consumer's expenditure on the first good change?
