Anyway, I can get some help with stating the principle of law and decision, and please explain your reasoning.

Chloe, who was 17 years old, purchased a used boat, agreeing to pay for it in monthly installments over a two-year period. During the next six months, she made 6 of the 24 payments she had agreed to make. The day before she celebrated her 18th birthday, she made the 7th payment. One month later, instead of making the regularly scheduled payment, she attempted to disaffirm the contract, claiming that she was a minor when she made the contract. (Chloe lived in a state where the age of majority is 18.) Is this a contract for necessaries? At what point did the contract become ratified, if it did at all? Is it likely that Chloe will be successful in her attempt to disaffirm the contract?

Thank you
