Solve for net exports in each row. b. Solve for aggregate expenditures (AE) in each row. C. State the value for the equilibrium GDP. d. If imports were to increase by $12000 so they are now equal to $23000, solve for net exports again. e. With this new export value, solve for aggregate expenditures in each row. f. State the value for the new equilibrium GDP. g. Solve for the multiplier (you can solve for either the actual or simple multiplier)
