There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 2000(250 - \frac{(3000 - x)}{15})\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{400}{3}x + 100000\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{400}{3}x + 100000\right)}{dx}\\=&\frac{400}{3} + 0\\=&\frac{400}{3}\\ \end{split}\end{equation} \]
