Hi I need help with some question regarding the case Vokes v. Arthur Murray.

SCENARIO:

Audrey Vokes went to a dance party offered by the Arthur Murray, Inc., dancing school, where she was persuaded to sign a contract for a dance course. Ms. Vokes was told she was an excellent dancer with grace and poise, and was encouraged to take more dance lessons. She was repeatedly talked into taking more dance courses by assurances that she was rapidly improving and developing in her dancing skills, and that additional lessons would make her a beautiful dancer, capable of dancing with the most accomplished dancers. Over a period of 16 months, Ms. Vokes took a total of 14 dance courses at a cost of over $31,000. In fact, Ms. Vokes had no skill as a dancer and her dancing did not improve with lessons. When she finally realized this, she sued the Arthur Murray dance school, claiming it had misled her to get her to sign a contract.

Questions:

What are the elements of a contract? How do the elements you identified apply to this case?
