While jogging around his suburb one morning, Pedro sees a speedboat parked outside a house. There is a sign posted on the boat’s windshield saying: “For sale $9,000, Text Andres on 0409876543. Direct buyers only!” A boat lover, Pedro calls the number advertised and leaves a voice message saying that he’s happy to buy the boat for $7,000. He also leaves his return number. Andres is busy all day, and only hears Pedro’s message the next morning. He calls Pedro back; he also leaves a voice message saying that Pedro’s price is too low, but he can get the boat for $8,000. That same day, however, another buyer sees the boat and makes a $9,000 cash offer to Andres on the spot. Andres takes the money, signs over the boat’s registration papers, and the buyer tows the boat away. Pedro passes by Andres’ house and sees that boat is gone. Panicking, he listens to his voice messages and hears Andres’ message for the first time. He calls Andres right away and told him in no uncertain words that he accepts his offer. Pedro now thinks he has accepted Andres’ offer so they now have a contract. When Pedro finds out that the boat has been sold to someone else, he gets very angry. He argues that he had already accepted Andres’ verbal offer, so he had no right to sell the boat to the other buyer. Does Pedro have a valid contract with Andres and he entitled to the boat? Explain with reference to all the elements of a valid contract
