Required:
1. What is the contribution margin for one custom skin?
2. How many custom skins must Kool-skins Company sell to break even?
3. If Kool Skins Company sells 12000 custom skins, what is the operating income?

McDuffy's Inc has developed a chew-proof dog bed-the McTuffie. Fixed costs are \$144000 per year. The average price for the McTuffie is \$32 and the average variable cost is \$24/unit. Currently, McDuffie produces and sells 20000 McTuffies.

Required:
1. How many McTuffies must be sold to break even?
2. If McDuffy wants to earn \$46000 in profit, how many McTuffies must be sold? Prepare a variable costing income statement to verify your answer.
3. Supposed that McDuffy would like to lower the break-even units to 12000. The company does not believe that the price or fixed cost can be changed. Calculate the new unit variable cost that would resulting in break-even units of 12000
4. What is McDuffy's current contribution margin and operating income? Calculate the degree of operating leverage (round to two decimal places) if sales increased by 10% next year. What would the percent change in operating income be? What would the new total operating income for next year be?
Sash Melton owns and operates The Green Belt Company (GBC), which produces live plants and flower arrangements to professional offices.

GBC chares \$60 per month for the average job.

Required:
1. How many jobs must GBC average each month to break even?
2. What is the operating income for GBC in a month with 65 jobs? With 90 jobs?
3. Sasha faces a tax rate quality to %30. How many jobs must Sasha have per month to earn an after-tax income of \$980? (round to nearest whole unit)
4. Suppose that Sasha's fixed costs increase to \$2500 per month and she decides to increase the price to \$75/job. What is the new break-even point in number of jobs per month? (round to the nearest whole number of jobs)

Required:
1. Calculate Sara's break even units
2. Prepare a profit-volume graph for Sara
3. Prepare a cost-volume-profit graph for Sara.
BB Company produces a variety of breads. The plant manager would like to expand production into sweet rolls as well. The average price of a loaf of bread is \$1. Anticipated price for a package of sweet rolls is \$1.50. costs for the new level of production are as follows:
Cost driver Unit variable cost Level of cost driver
Package of sweet rolls 0.93 -
Setups 300 250
Maintenance hrs 15 3500

Other data:
Total fixed costs (ABC) 57500
BB believes it can sell 600000 loaves of bread and 200000 packages of sweet rolls in the coming year.

Required:
1. Prepare a contribution-margin-based income statement for the next year. Be sure to show sales and variable costs by product and in total
2. Compute the break-even sales for the company as a whole using conventional analysis.
3. Compute the break0even sales for the company as a hole using activity-based analysis.
4. Compute the break-even units of each product in units. Does it matter whether you use conventional analysis or activity based analysis? Why or why not?
5. Supposed that VV could reduce the setup cost of \$100 per setup and could reduce the number of maintenance hrs needed to 1000. How many units of each product must be sold to break even in this case? (round to nearest whole unit)
