You can put this solution on YOUR website! year
1950 5650000 farms
2004 2110000 farms
Difference
54 -3540000
Increase in life expectancy per year = -3540000 / 54 = -65555.56
K(t)= 5650000 + -65555.556 t
2006 t= 56
K(t)= 5650000 + -65555.556 * 56
K ( 56 )= 1978888.89 farms
In 2006 it is expected to be 1,978,889
