There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 0.94 - \frac{0.06x}{(100 - x)}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = - \frac{0.06x}{(-x + 100)} + 0.94\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( - \frac{0.06x}{(-x + 100)} + 0.94\right)}{dx}\\=& - 0.06(\frac{-(-1 + 0)}{(-x + 100)^{2}})x - \frac{0.06}{(-x + 100)} + 0\\=& - \frac{0.06x}{(-x + 100)(-x + 100)} - \frac{0.06}{(-x + 100)}\\ \end{split}\end{equation} \]
