Leanne buys, refurbishes, and resells used mobile phones. She agrees to give a refurbished mobile phone from the her warehouse to Dell, a 17-year-old, if Dell promises to pay for the mobile phone by picking up trash in the company parking lot every day after school for the entire school year. Dell picks up the mobile phone from Leanne, then shows up after school and picks up trash for the first week of school. After that, he never shows up again and refuses to return the phone. Does the Leanne have a breach of contract claim against Delbert? 

No—because Dell was not the age of majority at the time of the contract, he is not liable. 

Yes—because Dell kept the phone, he is liable in contract. 

No--because Dell never signed a written agreement, and all contracts for the sale of goods must be in writing. 

Yes--because the agreement was supported by consideration.
