\[ \begin{array}{l} R_{1}=7.29+0.26 t+0.03 t^{2} \\ R_{2}=7.29+0.1 t+0.01 t^{2} \end{array} \] Which model projects the greater revenue? \( R_{1} \) projects the greater revenue. \( R_{2} \) projects the greater revenue. How much more total revenue does that model project over the six-year period? (Round your answer to three decimal places.) million
