Question
The general demand function for good A is Qd = 600 - 4PA - 0.03M - 12PB + 15T + 6PE + 1.5N where Qd
The general demand function for good A is
Qd = 600 - 4PA - 0.03M - 12PB + 15T + 6PE + 1.5N
where Qd = quantity demanded of good A each month, PA = price of good A, M = average household income, PB = price of related good B, T = consumer taste index ranging in value from 0 to 10 (the highest rating), PE = price consumers expect to pay next month for good A, and N = number of buyers in the market for good A.
