In the energy demand problem above, the demand vectors could be represented in a 2 row matrix, where row 1 contains the energy demands of the consumers and row 2 contains the energy demands of the energy industries:D = A new EPA mandate requires that all energy users reduce their energy use from the original level by over the next 10 years to minimize global warming. Use the matrix operations on a graphing calculator to calculate a new demand matrix which reflects this decrease.
