[Done] A company plans to sell a new type of vacuum cleaner for $280 each. The company's financial planner estimates that the cost, $y$, of manufacturing the vacuum cleaners is a quadratic function with a $y$-intercept of 11,000 and a vertex of (500, 24,000). Which system of equations can be used to determine how many vacuums must be sold for the company to make a profit? A. [tex]\left\{\begin{array}{l}y=280 x \\ y=-0,052(x-500)^2+24,000\end{array}\right.[/tex] B. [tex]\left\{\begin{array}{l}y=280 x \\ y=0.052 x^2+11,000\end{array}\right.[/tex] C. [tex]\left\{\begin{array}{l}y=280 x \\ y=0.052(x-500)^2+24,000\end{array}\right.[/tex] D. [tex]\left\{\begin{array}{l}y=280 x \\ y=-0.052(x-500)^2+11,000\end{array}\right.[/tex]
