Suppose that a consumer has the utility function u(:I;1,s:2) : {131.192, where 3:7; represents the quantity of good 3' consumed, i = 1, 2. The c0nsumer has exogenous income m = 50 and faces prices p1 : 1 and p2 : l for goods 1 and 2, respectively. Given the new prices, pa 2 3 and p3 = 4, What is the maximum amount that this consumer would be willing pay in order to prevent the price increases
