1. Suppose that there are two commodities and consider the consumption bundles a = (1,1), b = (2,2), c = (3,1), and d = (1,3).

(a) For an income of 2 and each of the three price vectors (1,1), (0.75, 1.5), and (1.5, 0.75), what pairs of consumption bundles can be possibly compared according to the "revealed to be preferred to" (abbreviated RP) relation?

(b) If instead income is 4, what can be said about pairs of commodity bundles where one of them can RP the other under the price vector (1,1)? What about price vector (2,2)?

Thanks so much!
