3. (10 Points) Suppose a town has a flour mill and a corn mill. Both mills operate to make their own style of tortillas. The flour mill requires $1 of corn for every $3 of flour. For every $1 of flour it produces, it must use $0.15 of flour (some goes to waste). The corn mill requires $2 of flour for every $1 of corn. For every $1 of corn it produces, it must use $0.09 of corn. The demand for its products requires the flour mill to produce $600 of flour and the corn mill to produce $900 of corn. Determine how much each industry should produce in order to meet the required demands. Again, no matrix multiplication/inverse matrix computation by hand is required, but be sure to show your work and required set-up of the problem. 4. (5 Points) Using the information from 3), how many dollars of flour input are required for every dollar of flour output? Explain how you know
