Question 3 [10 points] 1. Write down the own-price Slutsky equation in derivative form (for good I). [2 points] 2. Use your answer from part [1) to evaluate the following statement: \"If an increase in income has no effect on demand for a good, then the demand function can have either a positive or negative slope.\" [3 points] 3. Use your answer from part (1) to derive the elasticity form of the Slutsky equation. (Hint: this is a hard question, so leave it to the end. The elasticity form of the Slutsky equation should include the following elasticities: 5:32: the Marshallian own-price elasticity for good 3, Sim, the Hicksian own-price elasticity for good .13, and am, the income elasticity for good :12.)
