Drum Ltd. makes a single product, using a process involving stamping a circle out from sheet steel, covering it with hide and attaching it to a sidepiece.
For 2004 the standard materials costs and requirements have been as follows: 0.4 square metres of sheet steel at £5.20 per square metre; 0.8 square metres of hide at £9.20 per square metre; sidepiece at £4.20. Price increases relating to these raw materials have been notified for the year 2005. Sheet steel will fall in price by 10%, whilst hide will increase in price by 10% and the sidepiece will cost £5.
It takes 30 minutes of labour to punch out the metal, cut the hide and complete the assembly of the product. Labour currently costs the company £4 per hour, and this will increase by 4% with effect from 1 January 2005.
