Reese thinks peanut butter and chocolate are great when separate, but when they combine they are even more epic. In other words, Reese likes to eat either peanut butter or chocolate, but when he eats them together, he gets additional satisfaction from the combination. His preference over peanut butter (x) and chocolate (y) is represented by the utility function: u(x, y) = xy + x + y

Question

Reese thinks peanut butter and chocolate are great when separate, but when they combine they are even more epic. In other words, Reese likes to eat either peanut butter or chocolate, but when he eats them together, he gets additional satisfaction from the combination. His preference over peanut butter (x) and chocolate (y) is represented by the utility function:

u(x, y) = xy + x + y

**What is Reese’s Marshallian demand for chocolate, \( y^*(p_x, p_y, I) \)?**

(a) \( y^*(p_x, p_y, I) = \frac{I - p_y + p_x}{2p_y} \)

(b) \( y^*(p_x, p_y, I) = \frac{I}{2(p_y - p_x)} \)

(c) \( y^*(p_x, p_y, I) = \frac{I}{2p_y} - \frac{p_y}{p_x} \)

(d) \( y^*(p_x, p_y, I) = \frac{I + p_x}{2p_y} \)

(e) \( y^*(p_x, p_y, I) = \frac{I}{p_y} + \frac{p_x}{2} \)

This text presents a multiple-choice problem focused on calculating Marshallian demand, which is a concept in microeconomic theory used to determine consumer demand given prices and income. The question is specific to chocolate consumption by Reese, and different potential formulae (a-e) are proposed to describe this demand. Each option provides a mathematical expression involving the prices \( p_x \) and \( p_y \) and income \( I \).
