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:

The first phase of production has now been completed for the new television. The first unit actually took
12-5 hours to make and the total time for the first eight units was 34-3 hours, at which point the learning
effect came to an end.
What is the actual learning rate, and did the labour force learn more quickly or less quickly than…
