A product that is very labor intensive assembled at Boyds Aero Structure in Memphis has an average labor cost of $20/hr. Overhead expenses are charged at 100% of labor at this company. Time for the very first unit = 10 hours Time for the fourth unit = 8.1 hours The learning curve percentage for this operation is ?

A) 90%

Step-by-step explanation:

We know that by the learning curve, as cumulative output doubles the cumulative average time taken per unit decreases by a constant percent and the constant percent is the learning rate.

We need to double output 2 times in order to get from 1 to 4, so, we get the following:

The conclusion is that the learning curve for this operation is 90%.

56

step-by-step explanation:

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
