Write down your student number. Now label the non-zero digits starting from the right

to the left as A, B, C and so on. We only need 3. Use your A, B, and C in what follows, (just to be clear, if your number is 20567080 then A = 8, B = 7 and C = 6):

A consumer is known to consume the bundle (A, B, C, 8) when the price vector is (2, 2, 1, 1). The price vector changes to (1, 1, 2, 0.5). Can we tell if the consumer will be better off? Why or why not (i.e. argue the case and explain)?
