The neighbor replied that $250.00 was too much but she would pay that if Dave also pruned a large tee in her front yard. Dave said he would prune the tree, clean up the yard and clean the gutters but he would need to be paid $300.00 for all that work. The neighbor said she was not interested. Dave then said that he would prune the tree, clean up the yard and clean the gutters for $250.00, which he did the very next day. What is the legal issue in this case? (2 marks) Will the neighbor have to pay Dave? Why or why not? (2 marks)
