Since Jillian will spend $250 on books per year even if her income is zero, we start with an initial spending of $250. Then, as her income increases, she will spend 8% of each additional dollar of income on books. This can be represented mathematically as B = 250 + 0.08Y, where Y is her income and B is her spending on books. Therefore, the correct equation is C.
