The fixed cost of making clothes for a clothing store for three years is $40,000. the number of pieces of clothing bought per year is variable and ranges between 100 and 200 pieces of clothing. each garment is sold for $90. look at the five scenarios where random numbers were generated to show the number of garments for three years. scenario year 1 year 2 year 3 a 134 194 127 b 143 109 141 c 170 194 104 d 171 164 122 e 141 160 173 in which of these simulated scenarios is your total income less than your total cost? a

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?
