Sales and cost amounts are in thousands of dollars.
Part 2 Calculation of variable and fixed costs
Variable costs = = $0.40 per dollar of sales
Part 3
The estimates in Part 2 can be used to predict the total costs that will be

Part 4 Instructor note: Use equations in Exhibit 21.22 and 21.23 with predicted
numbers
(Fixed costs + Pretax income)
Required sales in dollars = Contribution margin ratio
= ($350,000* + $200,000**) / 60%***
= $550,000 / 60%
= $916,667 (rounded to the next dollar)
* 2013 fixed costs plus 2014 increase ($200,000 + $150,000) ..............................
$350,000
** Target after-tax income (given) ............................................................................
$140,000
Pretax target income = After-tax target income / (1 – Tax rate)
= $140,000 / (1 – 0.30) = $200,000
