Bobbi is planning a rectangular garden. The width of the garden will be 8 feet The length will be greater than the width. The area of the garden needs to be at least 100 square feet. George's garden will have the same width as Bobbi's garden, but the area will be at least 76 square feet. Part A Suppose z represents how much greater the length of Bobbi's garden is to its width. Which inequality can be used to find ? © 8(8x) >= 100 8(8 + x) >= 100 8x >= 100 (8+x)8>100

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?
