Furiosa has individual preferences for gasoline (G) and water (W), which can be represented by the following utility function: U(G,W) = 7G4W5 + 31.9

if the price of gas is $20, the price of water is $45, and furiosas income is $900, what is the optimal amount of gasoline?

Solutions

Expert Solution

The utility function is

Determine the Marginal utility of Gasoline by differentiating the utility function wrt G

Similarly calculate the Marginal utility of water by differentiating U wrt W, we get

At equilibrium the following relationship must hold true (Law of equimarginal criterion)

Plug in the values in the above expression

Given, Income =.$ 900

The budget constraint can be expressed as

Plug in the value of W in the above expression

Amount of Gasoline = 20

Amount of water = 11.11
