Gerald has two free-lance jobs. The income he can make from his first job can be represented by the function M(x) = 408x + 327, where x is the number of weeks he works. The income he can make from his second job can be represented by the function A(x) = x2 + 61x. Which function best describes D(x), the income he can make from both jobs? A. D(x) = 409x2 + 388x B. D(x) = x2 + 469x + 327 C. D(x) = 409x2 + 61x + 327 D. D(x) = x2 + 61x + 388

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
