Answer #1

Quantity demanded by consumer A = 50 - P = 50 - 30 = 20 units

Quantity demanded by consumer B = 50 - 2P = 50 - 2(30) = -10 units

Since there is nothing like negative amount of quantity demanded, consumer B will demand 0 units when price is $30.

Therefore, Total demand = Demand by consumer A + Demand by consumer B

= 20 + 0 = 20 units

C) 20 units

    5. Consider the following market demand for a good that consumers buy one unit at a time (e.g. smartphones, cars, game consoles, etc). Q=620-2P. A market research shows that there are two groups of consumers, A and B, with different sensitivity to price change. Group A’s demand is estimated to be QA=200-0.5P and Group B’s demand is estimated to be QB=420-1.5P. Marginal Cost is assumed to be $30. Given the information above, determine the most appropriate optimal pricing strategy and...
