The solution using Microsoft Excel functions is: Variable cost = Slope = $2.55 Fixed cost = Intercept = $160.85 Therefore, the cost formula is $160.85 per period plus $2.55 per unit of activity or: Y = $160.85 + $2.55X The solution using the formulas in the text is: n = 4 sumX = 183 sumY = 1, 110 sumXY = 50, 866 sumX^2 = 8, 405 b = [n(sumXY)- (sumX)(sumY)]/[n(sumX^2)- (sumX)^2] = [4(50, 866)- (183)(1, 110)]/[4(8, 405)- (183)^2] = $2.55 (rounded to nearest whole cent) a = [(sumY)- b(sumX)]/n = [(1, 110)- 2.55(183)]/4 = $161 (rounded to nearest whole dollar) Cost formula: Y = $161 + $2.55X.

(Appendix 2A)When analyzing a mixed cost, you should always plot the data in a scattergraph, but it is particularly important to check the data visually on a scattergraph when the R2 from a least squares regression is low.A quick look at the scattergraph can reveal that there is little relation between the cost and the activity or that the relation is something other than a simple straight line.
