... and the price of oil had increased from $8 to $16, then Demand: QD = -5 PG + (3.75) (16) = 60 - 5PG, and Supply: QS = 14 + 2PG + (0.25) (16) = 18 + 2PG. Equating supply and demand ... 0.6Qe=0.6(154 4-1 76P)=926. 4-1 05.6P. Graphically, export demand has pivoted inwards as illustrated in figure 2.5a below. Total demand becomes QD = Qd + 0.6Qe = 1700 - 107P + 926. 4-1 05.6P = 2626.4 - ... product. Given I=25, the demand curve becomes Q=30 0-2 P+4*25, or Q=40 0-2 P. Setting demand equal to supply we can solve for P and then Q: 40 0-2 P=3P-50 P=90 Q=220. b. If I=50, find the market clearing...
