Leticia invests $200 at 5% interest. if y represents the amount of money after x time periods, which describes the graph of the exponential function relating time and money? the initial value of the graph is 200. the graph increases by a factor of 1.05 per 1 unit increase in time. the initial value of the graph is 200. the graph increases by a factor of 5 per 1 unit increase in time. the initial value of the graph is 500. the graph increases by a factor of 2 per 1 unit increase in time. the initial value of the graph is 500. the graph increases by a factor of 1.02 per 1 unit increase in time.
the answer is 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?
