Problem 11-08 (algo) ADVANCED ANALYSIS Assume that the consumption schedule for a private open economy is such that consumption C=50+0.9Y. Assume further that planned investment I_(g), government spending G, and net exports x_(n) are independent of the level of real GDP and constant at I_(g)=30,G=0, and x_(n)=10. Recall also that, in equilibrium, the real output produced (Y) is equal to aggregate expenditures: Y=C+I_(g)+G+x_(n). Instructions: Round your answers to the nearest whole number. a. Calculate the equilibrium level of income or real GDP for this economy. $ b. What ha
