 Managerial Economics
1. Shelly accepts Corelli’s offer, assuming that the contract has met all of the requirements for a valid contract. The question is Corelli was a minor when he purchased the painting. Is the contract void? Is it voidable? What is the difference between these two concepts? A month after his eighteenth birthday Corelli decides that he would rather have $2,500 than the painting. He informs Shelly that he is disaffirming the contract and request that Shelly returned the $2,500 to him. When Shelly refuses to do so, Corelli brings a court action to recover the $2,500. What will the court likely decide in this situation? Why?
