Pharmacology graphs: Can both reach 80%?

An original curve-reading exercise: A has model Emax 100 and EC50 10; B has Emax 60 and EC50 1, all in arbitrary units. Which can produce a response of 80? A only: B's maximum is below 80. A lower EC50 does not imply greater maximal efficacy. These are constructed curves under identical model conditions, not measured drug data or a dosing guide.
