Parts 1 and 2
The scatter diagram and its estimated line of cost behavior appear below.
Sales and cost amounts are in thousands of dollars.
Part 2 Calculation of variable and fixed costs
Part 3
The estimates in Part 2 can be used to predict the total costs that will be
incurred at sales levels of 100 and 170 (both in thousands).

Part 3
When a business invests in fixed assets, as in this case, there is an increase
in its risk level (more fixed costs must be recovered). However, investments
in fixed assets can lower variable costs (as is the case here), which lowers its
break-even point, making it easier to make a profit with less sales.

2. As unit sales decline, Apple’s operating profits will fall by $300 per unit
versus Google’s decline in operating profits of $200 per unit. Thus,
operating profit will decline more for Apple than for Google as unit sales
decline.

1. There is no set solution for this problem. Answers will vary because each
student will make different estimates for groups, costs, and volume. The
instructor should make certain the student follows the correct steps in
preparing a multiproduct break-even analysis. This activity is designed to
show the student that several estimates are required in this type of CVP
analysis.
