Chapter F.1, Problem 69AYU

Poverty Threshold Poverty thresholds are 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 $2008$, the poverty threshold for a family of four with two children under the age of $18$ years was $\$21,834$. In $2016$, the poverty threshold for a family of four with two children under the age of $18$ years was $\$24,339$. 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 $2012$. How does your result compare to the actual poverty threshold in $2012$ of $\$23,283$?
