The prestigious consulting firm of Richard, Do and Dave ("RDD") has been hired by Sidney Blumenthal to construct a formula that will predict the total cost to the taxpayers of Ken Starr's continuing investigation into various alleged Clinton Administration misdeeds. Using elapsed time as the independent variable and news reports about the cumulative cost of Judge Starr's activities as the dependent variable, RDD has completed the first two steps of a scattergraph analysis. That is, they have plotted the data on a graph and have fitted a regression line through the points. Now RDD has to derive the formula that Mr. Blumenthal wants. RDD picked two points from their regression line: (9 months, $6,850,000), (15 months, $9,550,000). Based on RDD's research, the formula is: Y=2,800,000X+450,000, where Y is the elapsed time in months and X is the total cost of the investigation Y=450,000X+2,800,000, where Y is the total cost of the investigation and X is elapsed time in months Y=2,800,000X+450,000, where Y is the total cost of the investigation and X is elapsed time in months Y=450,000X+2,800,000, where Y is elapsed time in months and X is the total cost of the investigation
