There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 2500 + 0.02*2500 + (x - 25000)*0.04\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 0.04x + 1550\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 0.04x + 1550\right)}{dx}\\=&0.04 + 0\\=&0.04\\ \end{split}\end{equation} \]
