Answer #1

Answer : The answer is option A.

Here L = 3 x^0.90 y^0.80 - \lambda(8.00x + 5.00y - 200.00)

Now,

\deltaL / \deltax = 3 * 0.90 x^(0.90 - 1) * y^0.80 - \lambda * 8.00

=> \deltaL / \deltax = 2.70 x^-0.10 y^0.80 - 8.00\lambda

Therefore, option A is correct.

    solve 05 Question (5 points) See page 100 One of the most common functional forms used in economics is Cobb-Douglas. A Cobb-Douglas utility function takes the formu(I, y) = zºy , where 0 <a < 1. Note that we have imposed the condition that the exponents sum to 1. A monotonic transformation of the function could change that characteristic and still represent the same preferences. However, you will see below that having the exponents sum to 1 leads to a...

    Joyce's utility function is as follows: U= 10X2Y3 Where, X, is the quantity of good X consumed, Y, is the quantity of good Y consumed and, U, is Joyce's utility function. The general budget constraint for the two goods is a follow: B=PxX + PYY A. Derive Joyce's Marshallian demand equation for good X. Also compute her demand for good X when B= 500, and the price of good X is 1 and 2. Also draw the Marshallian demand curve...
