expanded vertically in $\backslash (20\backslash$times $1\backslash )$ by acquiring one of its suppliers of alloy steel plates, Keimer Steel Company. To manage the two separate businesses, the operations of Keimer are reported separately as an investment center. Garcia monitors its divisions on the basis of both unit contribution and return on average investment $($ROI$),$ with investment defined as average operating assets OBJECTIVE $4$ employed. Management bonuses are determined on ROI. All investments in operating assets are expected to earn a minimum return of $13$ percent before income taxes. Keimer's cost of goods sold is considered to be entirely variable, while the division's administrative expenses are not dependent on volume. Selling expenses are a mixed cost with $40$ percent attributed to sales volume. Keimer contemplated a capital acquisition with an estimated ROI of $14\mathrm{.}5$ percent; however, division management decided against the investment because it believed that the investment would decrease Keimer's overall ROI. The $\backslash (20\backslash$times $2\backslash )$ operating statement for Keimer follows. The division's operating assets employed were $\backslash (\backslash$$ $12,600,000\backslash )$ at November $30,20$x$2,$ a $5$ percent increase over the $\backslash (20\backslash$times $1\backslash )$ year$-$end balance. Required: $1.$ Calculate the unit contribution $($rounded to the nearest cent$)$ for Keimer Steel Company if $\backslash (1,187,000\backslash )$ units were produced and sold during the year ended November $\backslash (30,20\backslash$times $2\backslash ).$ Answer $\backslash (\backslash$downarrow $\backslash )$ Check Figures: Contribution margin $\backslash (=\backslash$$ $7,420,000\backslash )2.$ Calculate the following performance measures for $\backslash (20\backslash$times $2\backslash )$ for Keimer Steel Company: a$.$ Pretax return on average investment in operating assets employed $($ROI$)$ b$.$ Residual income calculated on the basis of average operating assets employed $3.$ Explain why the management of Keimer Steel Company would have been more likely to accept the contemplated capital acquisition if residual income rather than ROI were used as a performance measure. $4.$ Keimer Steel Company is a separate investment center within Garcia Industries. Identify several items that Keimer should control if it is to be evaluated fairly by either the ROI or residual income performance measures. $($CMA adapted$).$ Please include formulas and calculations I need to complete this in excel and am not very good with it$.$ Thank you so much
