Average visit per week equal 640 when the copayment is $40 and 360 when the copayment is $60.
A. Calculate the percentage change in visits, percentage change in price, and price elasticity of demand using 640 and $40 as the denominators for percentage change calculations.
B. Calculate the percentage change in visits, percentage change in price, and price elasticity of demand using 360 and $60 as the denominators for percentage change calculations.
C. Calculate the percentage change in visits, percentage change in price, and price elasticity of demand using 500 and $50 as the denominator for percentage change calculations. (This calculation funds finds the arc elasticity.)
D. How do your answers differ?
