Scenario 4.3: The demand for erasers (Q) is given as follows: Q = 240 - 4Pe + 2I + Pb + A where Pe is the price of erasers I is the level of income Pb is the price of another good A is the level of advertising Suppose that Q = 240, Pe = 10, Pb = 10, and A = 2. The point price elasticity of demand is -1/2. The price of the product increases from $1.00 to $1.10. Given the information in Scenario 4.3, the quantity demanded will decrease by approximately: A. 5 units. B. 5 percent. C. 10 units. D. 10 percent.
