purchase goldfish and other goods. My tastes are quasilinear in goldfish, and my utility function is U(g, y) = 50 g1/2 + y, where g is goldfish and y is other goods. The price of other goods is $1, and the price of goldfish is $5. My income is $500. At current prices, I purchase 25 goldfish and spend $375 on other goods.

Suppose that my income rises to $1,000. What is my new utility-maximizing choice of g and Y? What is my new utility?

Suppose that my income falls to $100. What is my new utility-maximizing choice of g and Y? What is my new utility?

Suppose that the price of goldfish rises to $10. What is my new utility-maximizing choice of g and Y? What is my new utility?

Suppose Peter has $500,000 to spend on a house and” other goods”(denominated in dollars). The price of 1 square foot of housing is $200, and Peter chooses to purchase optimally sized house at 1,250 square feet. Assume throughout that Peter spends money on housing solely for its consumption value (and not as part of his investment strategy). Suppose Peter’s tastes for ”square feet of housing” (x) and ”other goods” (y) can be represented by the utility function: u(x,y) = x1/2y1/2....
