In describing the cost formula equation Y = a + bX, which of the following statements is NOT correct? A As "X" increases "Y" increases. B "X" is the level of activity. In the high-low method, "b" equals change in activity divided by change in costs. "a" is the fixed component.

When the level of activity decreases, variable costs will:A - increase per unit.B - increase in total.C- decrease in total.D- decrease per unit

Show how each of these costs will behave as the volume of activity decreases.                                                  Variable cost per unit                                                  Total variable cost                                                  Fixed cost per unit                                                  Total fixed cost A. Increase B. Decrease C. Remains the same

On a cost-volume-profit graph, the revenue line will be shown below the total expense line for any activity level above the break-even point. FALSE O TRUE
