- Propose an acceptable structure that is consistent with the data.Explain why it is problematic to include a constraint such as the following in an LP model for a blending problem: Total octane in gasoline 1 blend $ divided by Barrels of gasoline 1 blended daily which is greater thanor equal to 10In this experiment, the problem is that the volume of the volumetric pipet is not accurately known (only 2 sig figs), so any density calculation will also be limited to 2 sig figs. Calibration increases the number of sig figs from 2 to 4. As a result, the density also increases from 2 to 4 sig figs. Explain how and why this is possible.
