When using the incremental unit-time learning model

	a.	the cumulative time per unit declines by a constant percentage when production doubles
	b.	the time needed to produce the last unit declines by a constant percentage when production doubles
	c.	the time to produce one additional unit decreases by a constant percentage
	d.	costs increase incrementally in an undetermined pattern

When the high-low method is used to estimate a cost function, the variable cost per unit is found by

	a.	performing regression analysis on the associated cost and cost driver database
	b.	subtracting the fixed cost per unit from the total cost per unit based on either the highest or lowest observation of the cost driver
	c.	dividing the difference between the highest and lowest observations of the cost driver by the difference between costs associated with the highest and lowest observations of the cost driver
	d.	dividing the difference between costs associated with the highest and lowest observations of the cost driver by the difference between the highest and lowest observations of the cost driver

The five-step decision process

	a.	includes planning and control activities
	b.	is performed exclusively by management accountants
	c.	is not often used, as the costs exceed the benefits
	d.	must be performed following GAAP guidelines

Refer to Try It 11-2 in your book on page 440. Looking at this using the Opportunity Cost Approach we have determined that the opportunity cost of accepting Victoria's offer is $26,000. Which element is not used in determining this $26,000

	a.	Variable marketing costs
	b.	Fixed marketing costs
	c.	Revenues
	d.	Variable costs of landscaping
