When Ken comes home from work one day, his neighbor Nick is waiting for him. "Your lawn is a mess," says Nick, "and you really should do something about it." Ken says, "I'm going on vacation tomorrow. Can you get someone to do a nice job on the lawn for me?" Nick says, "Sure." Nick hires Carlos, a professional landscaper to fix up Ken's lawn and yard. When Ken returns, Carlos presents him with a bill, which was a reasonable amount. Ken says that he never authorized Nick to promise that Ken would pay this amount. Is Ken obligated to pay Carlos? Yes, because of Nick's express authority. Yes, because of Nick's incidental authority. Yes, because of Nick's ratification authority. Yes, because of Nick's estoppel authority
