4. The United States Department of Agriculture tracks food availability in the country. In general, the amount of chicken available in the U. S. has been increasing steadily. In the year 2000, there were 54.2 pounds of chicken available per person, and in 2015, there were 62.6 pounds of chicken available per person. At the same time, the availability of red meat in the U. S. has been steadily decreasing. In 2000, there were 113.7 pounds of red meat available per person, and in 2015, there were 98.6 pounds of red meat available per person. Assuming these trends continue, and assuming that a linear function can effectively model these trends, predict the year in which chicken availability surpasses red meat availability.​
