8. Function C gives the cost, in dollars, of buying \( n \) apples. Which statement best represents the meaning of \( \mathrm{C}(10)=9 \) ? \( \begin{array}{ll}\text { a. The cost of buying } 9 \text { apples } & \text { b. The cost of } 10 \text { apples is } \$ 9 \\ \text { c. The cost of } 9 \text { apples is } \$ 10 & \text { d. Ten apples cost } \$ 9\end{array} \)

The statement that best represents the meaning of \( \mathrm{C}(10)=9 \) is \( \text{d. Ten apples cost } \$ 9. \) This notation indicates that when 10 apples are purchased, the total expense incurred is $9, making it clear and concise. As a fun little fact, did you know that apples have a rich history throughout different cultures? In ancient Greece, apples were considered symbols of knowledge and love, while in Norse mythology, they were seen as a source of immortality. Apples have certainly evolved from mythical icons to an essential part of our diets today!
