Qusetion: Mundo manufactures printing presses. Extra, a publisher of a local newspaper, had decided to purchase new presses. Rep, a representative of Mundo, met with Boss, the president of Extra, to describe the advantages of Mundo's new press. Rep also drew rough plans of the alterations that would be required in Extra's pressroom to accommodate the new presses, including additional floor space and new electrical installations, and Rep left the plans with Boss.

On December 1, Boss received a letter signed by Seller, a member of Mundo's sales staff, offering to sell the required number of presses at a cost of $2.4 million. The offer contained provisions relating to the delivery schedule, warranties, and payment terms but did not specify a particular mode of acceptance of the offer. Boss immediately decided to accept the offer and telephoned Seller's office. Seller was out of town, and Boss left the following message: "Looks good. I'm sold. Call me when you get back so we can discuss details."

Using the rough plans drawn by Rep, Boss also directed that work begin on the necessary pressroom renovations. By December 4, a wall had been demolished in the pressroom, and a contract had been signed for the new electrical installations.

On December 5, the President of the United States announced a ban on foreign imports of computerized heavy equipment. The ban removed-from the American market-a foreign manufacturer that had been the only competitor of Mundo. That afternoon, Boss received an email from Mundo stating, "All outstanding offers are withdrawn." In a subsequent telephone conversation, Seller told Boss that Mundo would not deliver the presses for less than $2.9 million.
