The table shows a recent graduate’s credit card balance each month after graduation.

\begin{array}{|c|c|c|c|c|c|c|c|c|}\hline \text{Month} & \text{1} & \text{2} & \text{3} & \text{4} & \text{5} & \text{6} & \text{7} & \text{8} \\ \hline \text{Debt ($)} & \text{620.00} & \text{761.88} & \text{899.80} & \text{1039.93} & \text{1270.63} & \text{1589.04} & \text{1851.31} & \text{2154.92} \\ \hline\end{array}
ⓐ Use exponential regression to fit a model to these data.
ⓑ If spending continues at this rate, what will the graduate’s credit card debt be one year after graduating?
