Find the particular antiderivative of each derivative that satisfies the given condition.

$$R'(x)=600-0.6x;R(0)=0$$

The goal of the exercise is to solve for the indefinite integral given that the derivative of the given function is

$$\begin{aligned} 600-0.6x \end{aligned}$$

and compute the arbitrary integration constant such that $R(0)\space \text{is} \space 0$.
