Your company has received an order for 20 units of aproduct. Th e labor cost to produce the item is $9.50 per hour. Th esetup cost for the item is $60 and material costs are $25 per unit. Th e item is sold for $92. Th e learning rate is 80 percent. Overheadis assessed at a rate of 55 percent of unit labor cost.(a) Determine the average unit cost for the 20 units if the fi rstunit takes four hours.(b) Determine the minimum number of units that need to bemade before the selling price meets or exceeds the averageunit cost.
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:

effect came to an end.

Your firm has an average cost of labor of $60/hour and the overhead is expected to run a fixed $1000 per session. The customer will pay you a flat fixed rate per session (Per Session Price.) If your profit markup is 12%, what will be the Total Price, the Per Session Price, and at what session will you break even? Answer the following four questions: What is the Total Price?
