iii) costs that decrease at a quicker rate than others

iii) Costs that are variable or fixed

iv) None of the above

3) When high-low method of estimating a cost behaviour pattern is used:

i) Cost and volume data should be reviewed for outliers

ii) Direct result of high-low calculations is fixed expense amount

iii) Highest and lowest sales price and volume amounts are used in the calculation

iv) the resulting cost formula will describe total cost accurately for every value between the high and low volumes

4) Shift in \ amount of manufacturing overhead costs applied to mix of products made which happens when using single cost driver rate as compared to using activity-based costing rates is called as:

i) Under applied overhead

ii) Over applied overhead

iii) Cost absorption

iv) Cost distortion

5) Excess of cost of goods manufactured over cost of goods sold for period represents:

i) Increase in gross profit

ii)  Decrease in work in process inventory

iii) Over applied manufacturing overhead

iv) Increase in finished goods inventory
