The general model for calculating a quantity variance is: actual quantity of inputs used x (actual price - standard price). standard price x (actual quantity of inputs used - standard quantity allowed for output). (actual quantity of inputs used at actual price) - (standard quantity allowed for output at standard price). actual price x (actual quantity of inputs used - standard quantity allowed for output).

The general model for calculating a quantity variance is:

	actual quantity of inputs used x (actual price - standard price).
	standard price x (actual quantity of inputs used - standard quantity allowed for output).
	(actual quantity of inputs used at actual price) - (standard quantity allowed for output at standard price).
	actual price x (actual quantity of inputs used - standard quantity allowed for output).

Answer
standard price x (actual quantity of inputs used - standard quantity allowed for output).
