The data used to develop the model came from a survey of 10 stores; for those data, SST (Total Sum of Squares) = 19,000 and SSR (Residual (error) St Squares) =5,510. What \% of the variability in sales has been explained by the two independent variables? Round your answer to two decimal places. For use \% sign when entering your answer.
