Given the demand function Q_X = 1500 - 100P_X + 75P_Y + 1.5I + .06A where P_Y = $40.00. I = $2500, and A = $5,000. When price of good X is increased from $60.00 to $75.00, what is the arc price elasticity of demand for good X over this range?

Question

Quizplus · Accepted Answer

The arc price elasticity of demand formula is used to calculate the elasticity between two points on the demand curve, which is given by the formula: $E_d = \frac{\% \Delta Q}{\% \Delta P}$. Given the demand function and the changes in price for good X from $60.00 to $75.00, we first calculate the change in quantity demanded at both prices and then apply the formula. However, without the specific calculations provided in the options, it's clear that the correct calculation isn't directly listed, leading to the choice of "none of the above."
