1) A Batch of 40 good workpieces is to be produced using a sand casting process with a starting material thatcosts $40 a piece. The time it takes to fill the mold is 10 seconds, while the solidification time is 1minute. The casting is removed from the sand mold in 5 seconds. The sand used to make the mold costs $100 and can be used to make 100 molds before it needs to be replaced by new sand. Making the moldwill take 20 minutes. Neglecting the melting process and assuming 5% scrap rate, then determine:

a) The production rate of the casting process.

b) The cost of each produce part given that• the hourly wage rate of the operator = $100/hr, and the applicable labor overhead rate =60%, and• the hourly equipment cost rate = $20/hr; which includes overhead.
