Study each of the following case. Answer the questions that follow with Yes or No.

Nguyen, 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. (Nguyen lived in a state where the age of majority is 18.)
a. Did Nguyen’s first six payments indicate her ratification?
b. Is this a contract for necessaries?
c. Did the seventh payment serve to ratify the contract?
d. Is it likely that Nguyen will be successful in her attempt to disaffirm the contract?
