The Nowra Company has assembled the following data pertaining to certain costs that cannot be easily identified as either fixed or variable. Nowra Company has heard about a method of measuring cost functions called the high-low method and has decided to use it in this situation.

	Month	Cost	Hours
	January	$40 000	3500
	February	24 400	2000
	March	31 280	2450
	April	36 400	3000
	May	44 160	3900
	June	42 400	3740

How is the cost function stated?

	a.	y = $21 360 + $1.52X
	b.	y = $10 112 + $8.64X
	c.	y = $26 672 + $1.84X
	d.	y = $3600 + $10.40X
	e.	No correct answer
