Question 1 YUX Corporation sells a single product for $50. Its management estimates the following revenues and costs for the year 2020: Net sales $540,000 Selling expenses-variable $21,900 Direct materials 209,500 Selling expenses-fixed 20,300 Direct labour 61,300 Administrative expenses-variable 9,500 Manufacturing overhead-variable 21,800 Administrative expenses-fixed 9,100 Manufacturing overhead-fixed 13,800 Assuming fixed costs and net sales are spread evenly throughout the year, determine YUX's monthly break-even point in units and dollars. ( Round answers to 0 decimal places, e.g. 5,275.) Monthly break-even in units units Monthly break-even in dollars $ Calculate the contribution margin ratio, the annual margin of safety ratio, and the annual profit. ( Round answers to 0 decimal places, e.g. 15 or 15%.) Contribution margin ratio Annual margin of safety ratio Annual profit $Determine the percentage increase in annual profits if YUX Corporation increases its selling price by 20% and all other factors (including demand) remain constant. (Round answer to 2 decimal places, e.g. 15.25%.) Percent increase in profit % Assume the price remains at $50 per unit and variable costs remain the same per unit, but fixed costs increase by 20% annually. Calculate the percentage increase in unit sales required to achieve the same level of annual profit calculated in part (b). (Round answer to 2 decimal places, e.g. 15.25%.) Percent increase in unit sales Determine the sales required to earn an operating income of $372,000 after tax. YUX Corporation's income tax rate is 40%. Sales required to earn an operating income of $372,000 $
