Problem $4-22$ Break$-$Even Analysis; Target Profit Analysis; Margin of Safety; CM Ratio $[$LO$1,$ LO$3,$ LO$5,$ LO$6,$ LO$7]$ Menlo Company distributes a single product. The company's sales and expenses for last month follow: Required: $1.$ What is the monthly break$-$even point in unit sales and in dollar sales? $($Do not round intermediate calculations.$)2.$ Without resorting to computations, what is the total contribution margin at the break$-$even point? $3-0.$ How many units would have to be sold each month to earn a target profit of $\backslash (\backslash$$ $93,600\backslash )?$ Use the formula method. $3-$b$.$ Verify your answer by preparing a contribution format income statement at the target sales level. $/$r$/$n $4.$ Refer to part $3$ and now assume that the tax rate is $\backslash (30\backslash \%\backslash ).$ How many units would need to be sold each month for an after$-$tax target profit of $\backslash (\backslash$$ $93,600\backslash )?($Round the final answer to the nearest whole number.$)5.$ Refer to the original data. Compute the company's margin of safety in both dollar and percentage terms. $($Round your percentage answer to $2$ decimal places.$)6.$ What is the company's CM ratio? If sales increase by $\backslash (\backslash$$ $52,000\backslash )$ per month and there is no change in fixed expenses, by how much would you expect monthly net operating income to increase? $($Round your percentage answer to $2$ decimal places and other answer to the nearest whole dollar amount.$)$
