Chapter 1.5, Problem 34E

Population distribution Using U.S Census Bureau data (and projections to 2050), the percent of the U.S population that is Black $B\left(x\right)$ and Hispanic $H\left(x\right)$ can be described by

$B\left(x\right)=0.057x+12.3$ and $H\left(x\right)=0.224x+9.01$

Where $x$ is the number of years past 1990.

In what year were the percents of these groups equal? What was the percent of each ?

Do these models indicate that there were more Blacks or more Hispanics in 2012?
