(CVP single product—comprehensive) Louis Mouse Technology makes a special low-cost mouse for computers. Each mouse sells for $25 and annual production and sales are 120,000 units. Costs for each mouse are as follows:

a. Calculate the unit contribution margin in dollars and the contribution margin ratio for the product.

b. Determine the break-even point in number of mice.

c. Calculate the dollar break-even point using the contribution margin ratio.

d. Determine Louis Mouse Technology’s margin of safety in units, in sales dollars, and as a percentage.

e. Compute Louis Mouse Technology’s degree of operating leverage. If sales increase by 25 percent, by what percentage would before-tax income increase?

f. How many mice must the company sell if it desires to earn $996,450 in before-tax profits?
g. If Louis Mouse Technology wants to earn $657,800 after tax and is subject to a 20 percent tax rate, how many units must be sold?
h. How many units would the company need to sell to break even if its fixed costs increased by $7,865? (Use original data.)
i. Louis Mouse Technology has received an offer to provide a one-time sale of 4,000 mice to a network of computer superstores. This sale would not affect other sales or their costs, but the variable cost of the additional units will increase by $.60 for shipping and fixed costs will increase by $18,000. The selling price for each unit in this order would be $20. Based on quan¬ titative measurement, should the company accept this offer? Show your calculations.LO1
