You sell $89.50 worth of drinks at a concession stand by selling x small, 29 medium, and 12 large drinks. Write an equation you can use to find the number of small drinks you sold.

On a piece of paper graph f(x)=5•(0.4)^x

The graph shown is the graph of which function?

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?
