The data can be modeled by the quadratic function $y=a t^{2}+b t+c$ .Create a system of linear equations for the data.Let t represent the year,with t = 10 corresponding to 2010.

• A) \[\left\{ \begin{array} { l }
• 100 a + 10 b + c = 13.83 \\
• 121 a - 11 b + c = 14.07 \\
• 144 a + 12 b + c = 14.23
• \end{array} \right.\]
• B)​ \[\left\{ \begin{array} { l }
• 100 a - 10 b + c = 13.83 \\
• 121 a + 11 b + c = 14.07 \\
• 144 a + 12 b + c = 14.23
• \end{array} \right.\]
• C)​ \[\left\{ \begin{array} { l }
• 100 a + 10 b + c = 13.83 \\
• 121 a + 11 b + c = 14.07 \\
• 144 a + 12 b + c = 14.23
• \end{array} \right.\]
• D)​ \[\left\{ \begin{array} { l }
• 100 a + 10 b + c = 13.83 \\
• 121 a + 11 b + c = 14.07 \\
• 144 a + 12 b - c = 14.23
• \end{array} \right.\]
• E)​ \[\left\{ \begin{array} { l }
• 100 a - 10 b - c = 13.83 \\
• 121 a - 11 b - c = 14.07 \\
