To translate a statement such as ‘The sum of twice a number and 6 is equal to the difference of the number and 9’ write an equation using the definitions of the terms used. For example, sum means to add and difference means to subtract. The result is 2x+6=x-9. Develop your own statement such as the one above. Include at least four mathematical operations. Write an equation to represent the problem you develop.

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?
