True or False On March 7, 2020, John sends Mary an email as follows:

"I promise to wash your pickup truck on Saturday, March 14, 2020, for $50."

Mary does not reply to John's

message. John shows up on March 14, and

washes Mary's pickup truck. When Mary comes home on the bus, she finds her

clean truck, and a note from John that says: "You owe me $50. John"

Assume that Mary refuses to pay John. If John takes Mary to court, the judge

will probably rule that they had a contract, and that Mary owes the $50 to John.
