I need help with these multiple choice questions. Some I have narrowed down a couple options on but I can't figure out which of the two are the best answer. Any and all help so appreciated :)

____ A. B. C. D. 8. The contribution margin ratio measures: Profit per unit Contribution margin per dollar of sales Profit per dollar of sales The ratio of variable to fixed costs ____10. In the cost allocation process, an allocation base: A. Must be some characteristic that is common to all of the cost objectives. B. Ideally should result in cost being allocated based on a cause-and-effect relationship. C. Both A and B. D. None of the above. ____11. Allocation of indirect costs: A. Can be done with great accuracy and precision, if the proper techniques are used. B. Is an inherently arbitrary process, a characteristic that can lead to problems. C. Can often be justified in a variety of ways that lead to substantially different costs being allocated. D. Both B and C. ____12. Controllable costs for the manager of Production Department A include: A. Costs of the finance department. B. Costs of material and labor used in Department A. C. All costs related to Department A's final product. D. All of the above. ____13. Activity-based cost systems: A. Always lead to improvements in cost control. B. Are less expensive to develop and maintain than traditional costing systems. C. Allow managers to see the costs of key activities. d. Are used to develop the full cost of products, which provides clear information for decision-making. ____14. Which of the following costs should not be taken into consideration when making a decision? A. Opportunity costs B. Sunk costs C. Relevant costs D. Differential costs ____15. To determine the profit-maximizing price, a manager must: A. Estimate the quantity demanded for various prices. B. Estimate variable costs. C. Both A and B are correct. D. None of the above are correct. Please match the numbered terms with their definitions by placing the letter that identifies the best definition in the blank space next to the term. ____ 1. Absorption Costing ____ 2. Activity-Based Costing (ABC) ____ 3. Contribution Margin ____ 4. Cost-Volume-Profit Analysis ____ 5. Direct Costs ____ 6. Fixed Costs ____ 7. Cost Driver ____ 8. Incremental Analysis ____ 9. Incremental Costs ____ 10. Indirect Costs ____ 11. Just-In-Time (JIT) Manufacturing ____ 12. Mixed Costs ____ 13. Opportunity Costs ____ 14. Period Costs ____ 15. Product Costs ____ 16. Regression Analysis ____ 17. Sunk Costs ____ 18. Variable Costs ____ 19. Variable Costing ____ 20. Activity-Based Pricing A. Costs that are directly traceable to a product, activity, or department. B. Costs that do not change when there is a change in business activity. C. An analysis of the revenues and costs that will change if a decision alternative is selected. D. Costs that either are not directly traceable to a product, activity, or department, or are not worth tracing. E. The values of benefits foregone by selecting one decision alternative over another. F. Costs incurred in the past - they are irrelevant to current decisions. G. A method of assigning overhead costs that identifies key activities and accumulates the costs associated with them. H. A manufacturing system designed to minimize inventories of raw materials and works in process. I. Costs identified with accounting periods rather than with goods produced. J. Costs assigned to goods produced. K. The difference between sales and variable costs. L. The analysis of how costs and profit change when volume changes. M. A statistical technique that can be used to estimate the intercept (an estimate of fixed cost) and the slope (an estimate of variable cost) of a cost equation. N. Costs that increase or decrease in response to increases or decreases in business activity. O. Costs that contain both variable and fixed costs elements. P. An approach to product costing that includes direct material, direct labor, and both fixed and variable manufacturing overhead. Q. A measure of the activity, related to a cost pool, that is used to allocate cost. R. An alternative to full costing in which only variable production costs are included in inventory. S. Costs that increase or decrease if a decision alternative is selected. T. An approach to pricing in which customers are presented with separate prices for services they request in addition to the cost of goods they purchase
