while in chicago, brent and margaret plan on visiting the willis
tower, built as and still commonly referred to as the sears
tower.
in the lobby, there is a model of the sears tower that has an
observation deck with a height of 4 meters. if the actual height
of the observation deck is 412 meters, what is the scale of the
model?

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?
