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

B(x) = 0.057x + 12.3 and H(x) = 0.224x + 9.01

where x is the number of years past 1990.

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

(b) Do these models indicate there are more Blacks or more Hispanics in 2012?
