Please answer each subquestion in an Excel tab (show excel equations!!!) A severe winter ice storm has swept across Virginia and North Carolina, followed by over a foot of snow and frigid, single-digit temperatures. These weather conditions have resulted in numerous downed power lines and power outages in the region causing dangerous conditions for much of the population. The electricity company VNC has been overwhelmed and have requested assistance from unaffected five utility companies from Tennessee, Kentucky, and West Virginia. The following table shows the number of utility trucks with crews available from five different companies; the demand for crews in six different regions that VNC cannot get to; and the weekly cost ($1,000s) of a crew going to a specific area (based on the visiting company's normal charges, the distance the crew has to come, and living expenses in an area): From To NC-1 NC-2 NC-3 VA-1 VA-2 VA-3 Total Supply WV-1 $ 15.2 $ 14.7 $ 16.1 $ 13.2 $ 12.7 $ 14.1 12 WV-2 $ 14.3 $ 13.9 $ 15.2 $ 14.2 $ 14.0 $ 14.8 15 TN-1 $ 10.9 $ 10.3 $ 10.7 $ 11.7 $ 13.4 $ 13.4 13 TN-2 $ 11.1 $ 11.1 $ 12.4 $ 13.0 $ 14.2 $ 14.0 16 KY-1 $ 12.7 $ 13.2 $ 15.0 $ 14.0 $ 12.8 $ 14.3 18 14 16 13 9 10 12 74 Total Demand (The cost is in $1,000s) Determine the number of crews that should be sent from each utility to each affected area that will minimize total costs.
