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 boom in the economy causes an across the board increase of 10% in energy demands in the area. Calculate a new demand matrix which reflects this increase.
What will be an ideal response?
