Question 8

A significant weakness of the high-low method is that

	a.	a significant amount of management expertise is necessary to break out the variable and fixed costs.

	c.	the calculations are so complex that a computer is usually necessary in order to get accurate results.
	d.	monthly data must be collected for at least three years before the method can be used.
