8. If one increases variable costs per unit, the break-even point will decrease.
9. The impact on a firm’s income resulting from a change in the number of units sold can be assessed by
multiplying the unit contribution margin by the change in units sold assuming that fixed costs remain

10. To find the number of units to sell to earn a targeted income, it is acceptable to simply adjust the

11. To determine the number of units that must be sold to earn a target operating income, one can use the

12. The contribution margin income statement provides a good check to determine if the sale of a certain
number of units really results in operating income of the given amount.
13. If fixed costs increase, the break-even point decreases.
