Marco's utility from good X and good Y is given by the function U (x, y) = IU, his marginal utilities are MUx= yand MUy = I. Given that Marco's income is $12, the following three prices for good X, Px = $2, Px = $3, and Px = $4 and that Py = $1, what are three
points on Marco's demand curve for good X? (Note: points are in (quantity, price)
format.)
a. (3, 2), (2, 3), and (3, 4) b. (2, 6), (3, 2), and (4,3) c. (6, 2), (2, 3), and (3, 4) d. (2, 3), (2, 3), and (6, 2)
