When a consumer has quantities, ₁ and ₂, of apples and oranges respectively, his utility is given by u(x1, x₂) 2/3 1/3 = X1 X₂ .

When a consumer has quantities, x1 and 2, of apples and oranges respectively, his
utility is given by
u(x1, x2)
2/31/3
X1 X2
Given that each apple costs pi dollars and each orange costs p2 dollars, use the method
of Lagrange multipliers to find the bundle of goods, (x1, x2), that will maximise his
utility given that he spends M dollars on apples and oranges.
[You are not required to justify the use of the method of Lagrange multipliers here.]
Also find his maximum utility, U(M), and verify that U'(M) is equal to the value of
the Lagrange multiplier.
