Scientists classify stars according to the following categories: O, B, A, F, G, K, M. A star's category depends upon its spectral type, which is determined by its temperature. The chart below shows five stars of different categories, along with their temperatures. $$ \begin{array}{|l|l|} \hline \text { Star Type } & \text { Temperature }\left({ }^{\circ} \mathbf{F}\right) \\ \hline \text { O } & 18,033 \\ \hline \text { B } & 9,978 \\ \hline \text { A } & 4,839 \\ \hline \text { F } & 3,644 \\ \hline \text { G } & 3,422 \\ \hline \end{array} $$ However, rather than measuring star temperature in degrees Fahrenheit, scientists typically measure star temperature in units of Kelvin. The conversion from Fahrenheit to Kelvin is given by the following formula: $$ \mathrm{K}=\frac{5}{9}\left({ }^{\circ} \mathrm{F}-32\right)+273 $$ What is the approximate temperature of the A-type star in Kelvin? You may use a calculator. A. 2,569 B. 2,822 C. 2,929 D. 2,944
