1.4 David consumes two things: gasoline (G) and bread

(B). David’s utility function is U(q1, q2) = 10q1 0.25q2 0.75.

a. Derive David’s demand curve for gasoline.

b. If the price of gasoline rises, how much does David reduce his consumption of gasoline, 0q1/ 0p1?

c. For David, how does 0q1/ 0p1 depend on his income? That is, how does David’s change in gasoline consumption due to an increase in the price of gasoline depend on his income level?

To answer these questions, find the cross-partial derivative, 02q1/(0p1 0Y). m
