Consider an economy similar to that in the preceding question in which investment is also $200, government purchases are also $500, net exports are also $30, and the price level is also fixed. But taxes now vary with income and, as a result, the consumption schedule looks like the following: GDP Taxes DI C $1,360 $320 $1,040 $810 1,480 360 1,120 870 1,600 400 1,200 930 1,720 440 1,280 990 1,840 480 1,360 1,050 Find the equilibrium graphically.
