__________(1) The amount that the sale of one unit contributes toward recovering fixed costs
and earning profit.
__________(2) A cost that changes in proportion to changes in volume of activity.
__________(3) A cost that includes both fixed and variable costs.
__________(4) A cost that changes with volume, but not at a constant rate.
__________(5) A line drawn on a graph to fit the past relation between cost and sales.
__________(6) A statistical method for deriving an estimated line of cost behavior that is
more precise than the high-low method and a scatter diagram.
__________(7) A company’s normal operating range; excludes extremely high and low
volumes that are not likely to be encountered.
__________(8) A cost that remains constant over limited ranges of volumes of activity but
changes by a lump sum when volume changes occur outside these limited ranges.
__________(9) Useful in business planning; includes predicting the volume of activity, the
costs incurred, sales earned, and profits received.
__________(10) A cost that remains unchanged in total amount even when the volume of
activity varies.
