Budgeted production ......................................................................................... 1500 units 

Direct material cost: 7 kg x £4.10 ..................................................................... £28.70 per unit 

Actual results for the period were as follows: 

Production ..........................................................................................................  1600 units 

Direct material (purchased and used): 12 000 kg  ........................................  £52 200 

It has subsequently been noted that due to a change in economic conditions the best price that the material could have been purchased for was £4.50 per kg during the period.
