Scenario 5.1 The Demand for Noodles Is Given by the Following Equation

Scenario 5.1
The demand for noodles is given by the following equation: Q = 20 - 4P + 0.2I - 2P_x. Assume that P = $8, I = 200, and P_x = $10.
-Cross-price elasticity is represented by the formula ΔQ/ΔP × P/Q; where Q and ΔQ represent the quantity demanded and change in quantity demanded of a good, and P and ΔP represent the price and change in price of a related good respectively.
