Determine a linear trend line for expected freight car loadings. (Round your intermediate calculations and final answers to 2 decimal places.) b. Use the trend equation to predict expected loadings for weeks 20 and 21 (Round your final answers to 2 decimal places.) and The forecasted demand for week 20 and 21 is respectively A c. The manager intends to install new equipment when the volume exceeds 800 loadings per week. Assuming the current trend continues, the loading volume will reach that level in approximately how many more weeks? (Use the rounded answers, as required, from any previous part of this problem. Do not round any other intermediate calculations. Round your final answer to 2 decimal places.) It would take approximately more weeks.
