The manufacturing process of a new product is very labor intensive. The learning curve percentage (LC) for the process is 90%. It took 30 hours with 15 workers together to produce the first product. The average labor cost including overhead expenses is about $20 per hour.
(a) Estimate the labor cost (including overhead expenses) to produce the tenth product? (Hint: 2 steps. How long is T_10? How much is the cost?)
(b) A new training program is intended to lower the learning-curve percentage by 10% (minus 10%). If the program is successful, what cost savings will be realized for the tenth unit? (Hint: How long is the new T_10? How much is the new cost? How much is the cost saving?)

- The following scenario relates to 5 questions. Bear Co has developed a new model of television. The estimated labour time for the first unit is 12 hours but a learning curve of 75% is expected to apply for the first eight units produced Note: The learning index for a 75% learning curve is-0-415. Overhead production costs must be estimated based on a previous model, the Leonardo, that was made by Bear Co. Production quantities and total overhead costs for the last four months of production of the Leonardo were as follows: Month Output Total overhead cost (units) $ September 1,800 278,200 October 2,000 310,000 November 1,700 252,900 December 1,000 200,000 The first phase of production has now been completed for the new television.
