Consider a closed economy with tarming and building sectors. The building sector consumes 20 percent of its own production, with the remainder going to the farming sector. The farming sector consumes 70 percent of its own production, with the remainder going to the building sector. In your answer below, keep the columns and rows in alphabetical order (building, then farming). The exchange matrix for this economy is E= Find the general solution of the closed Leontief equation ( EI)X=0 and enter it below. Recall that we did this by writing the system in augmented matrix form and using Gauss-Jordan elimination. If everything goes well, your solution should have one parameter, t. The general solution is X= If the farming sector's total production of goods this year is 70000 dollars, the building sector must produce dollars worth of goods to keep the economy in equilibrium..
