5. Individual Consumer’s Demand Qd X = f(P X , I, P Y , T) quantity demanded of commodity X by an individual per time period price per unit of commodity X consumer’s income price of related (substitute or complementary) commodity tastes of the consumer Qd X = P X = I = P Y = T =
6. Qd X = f(P X , I, P Y , T) Qd X / P X < 0 Qd X / I > 0 if a good is normal Qd X / I < 0 if a good is inferior Qd X / P Y > 0 if X and Y are substitutes Qd X / P Y < 0 if X and Y are complements

10. Market Demand Function QD X = f(P X , N, I, P Y , T) quantity demanded of commodity X price per unit of commodity X number of consumers on the market consumer income price of related (substitute or complementary) commodity consumer tastes QD X = P X = N = I = P Y = T =

13. Linear Demand Function Q X = a 0 + a 1 P X + a 2 N + a 3 I + a 4 P Y + a 5 T P X Q X Intercept: a 0 + a 2 N + a 3 I + a 4 P Y + a 5 T Slope: Q X / P X = a 1
14. Linear Demand Function Example Part 1 Demand Function for Good X Q X = 160 - 10P X + 2N + 0.5I + 2P Y + T Demand Curve for Good X Given N = 58, I = 36, P Y = 12, T = 112 Q = 430 - 10P
