Certified farmland increased 42 percent from 1997 to 2002. The graph shows that in 2002, there were about 600,000 acres of pasture and 1,300,000 acres of cropland, for a total of about 1,900,000 acres. That’s 42 percent more than in 1997: 1,900,000 = 1.42x; x = 1,338,028 acres in 1997. The ratio of pasture to cropland was the same in 1997 as in 2006. In 2006, there were just a little over 1,000,000 acres of pasture— call it about 1,050,000 acres— and 1,900,000 acres of cropland, for a ratio of 10.5 to 19 or, eliminating the decimal, 21 to 38. Therefore, the ratio of pasture to all acreage is 21:( 21 + 38) or 21: 59. That can
be expressed as 21/59 or about 0.36. Total acreage in 1997 was 1,338,028. Multiply: 1,338,028 × 0.36 = 481,690.
% change \(\frac{2,200,000-500,000}{500,000} =340\)
E is the answer
