Chapter 1.1, Problem 117AE

Poverty Threshold Poverty thresholds arc determined by the U.S. Census Bureau. A poverty threshold represents the minimum annual household income for a family not to be considered poor. In 2005, the poverty threshold for a family of four with two children under the age of 18 years was $\$19,350$. In 2015, the poverty threshold for a family of four with two children under the age of 18 years was $\$24,250$. Assuming poverty thresholds increase in a straight-line fashion, use the midpoint formula to estimate the poverty threshold of a family of four with two children under the age of 18 in 2010. How does your result compare to the actual poverty threshold in 2010 of $\$22,050$?
