Velocity is V, the quantity of money is M, the price level is P, and real GDP is Y. Which of the following formulas is correct? OV= (P x Y) +M OV=(P + Y) XM OY= VXM O Y = (P x M) + V O Y= (P + M) - VSuppose nominal GDP is $2,000 a year and the quantity of money is $400. Then the velocity of circulation equals O 5. O 1/5. O 10 O 2. O 8
