Plain-text version

Let e, R, and p represent own price elasticity of demand, total revenue, and price, respectively for a good. If (∂ R)/(∂ p)<0, then (A) |e|>1 (B) |e|=1 (C) |e|<1 (D) |e|=0

Also written as: Let e, R, and p represent own price elasticity of demand, total revenue, and price, respectively for a good. If (d R)/(d p)<0, then
