The salary is a mixed cost. Notice that the cost per unit and in total for each volume level are
not the same. There is a variable cost component of P10 per unit and a fixed cost component
of P10,000. Within a relevant range, unit variable cost as well as total fixed cost are constant.
Variable cost (30,000 – 20,000) ÷ (2,000 – 1,000)

Activity Cost Analysis
51 . Answer: C
To analyze mixed cost using high-low method, the analyst always identifies and uses the
lowest and the highest levels of activities. The reason is that the activity presumably causes
costs, so the analyst would like to use data that reflects the greatest possible variation in
activity.
52 . Answer: D
The question does not require a computation. R2 (goodness of fit) indicates the percentage of
the variation in the dependent variable (cost) that is explained by variation in the independent
variable (activity). The adjusted R2 varies from zero to 100%, and the higher the percentage,
the better.
