Suppose the money supply M has been growing at 10% per year, and nominal GDP, PY, has been growing at 20% per year. The data are as follows (in billions of dollars):

	2010	2011	2012
M	100	110	121
PY	1,000	1,200	1,440
V

Complete the table above by calculating the velocity V in each year. (Round your responses to the nearest whole number.)
