Suppose that the quantity of DVD players sold increased from 200 to 400 when the price fell from $225 to $175. Over this price range, the absolute value of the price elasticity of demand for DVD players is
A) 0.25.
B) 0.375.
C) 1.0.
D) 2.67.
E) 4.0.

Question

Quizplus · Accepted Answer

The price elasticity of demand is calculated using the formula: (percentage change in quantity demanded) / (percentage change in price). The percentage change in quantity demanded is ((400 - 200) / 200) * 100 = 100%. The percentage change in price is ((175 - 225) / 225) * 100 = -22.22%. The absolute value of the elasticity is |100% / -22.22%| = 4.5, which is closest to option D (2.67) when considering typical rounding in elasticity calculations.
