The managers at Fairfield Engines want to find out the total cost of producing 16 engines. The first unit requires 50 labor-hours and the company expects a learning curve of 80%. The labor cost per hour is $12 and associated overhead costs are $20 per labor hour.
a. Assuming the cumulative average-learning model, what will be the total cost of producing 16 engines?

The total cost for conversion considering a learning curve of 80%

will be of $ 14,272 plus materials

Explanation:

cost of the first unit:

50 labor hours x ($20 wages + $12 overhead) = $1,600

As there is a learning curve of 80% the cost will reduce at that rate each time the production doubles

We have to solve this as the sum o the time it takes for each product to be produced:

where n is the numebr of unit

446 hours labor hours x ($20 wage rat + $12 MO) =

$ 14,272
