Sharon wanted a video camera so she could record her son's soccer games and birthday parties. Reliable TV, a retailer, sold a digital video recorder to Sharon. The recorder has a one year warranty. Sharon paid with a negotiable promissory note. Later, Reliable TV properly negotiated and sold Sharon's note to First Finance Co, Sharon's recorder broke six months after she bought it. Reliable TV failed to honor its warranty, so Sharon stopped making payments on the note. First Finance has sued to force Sharon to pay on the the note it bought from Reliable TV. The outcome of this case is that: First Finance wins because a proper negotiation cuts off any defenses against payment that the maker (Sharon) had.  Explain how much advantage did Sharon kept? Also explain the income tax of Sharon.
