A factory selling cell phones has a marginal cost function $\displaystyle {C}{\left({x}\right)}={0.01}{x}^{{2}}−{3}{x}+{229}$, where $\displaystyle {x}$ represents the number of cell phones, and a marginal revenue function given by $\displaystyle {R}{\left({x}\right)}={429}−{2}{x}$. Find the area between the graphs of these curves and $\displaystyle {x}={0}$.



What does this area represent?
