Consider an economy with the given equations. Y=C+I+G+NX G=$IOOO T=$IOOO 1=1000-50r In this economy, solve for private saving, public saving, national saving, investment, and the -$ trade balance Private saving= $ Private saving= $ National Saving= $ Investment= $ Net Exports= $ Suppose now that G rises to $1350. Solve for private saving, public saving, national saving, investment, and the trade balance. Private saving is now= $ Net exports (trade balance) - Public savings = $ National savings = $ Investment = $
