Step-by-step explanation:
In general, if the learning curve is p%, then the time
estimated to produce the nth unit is given by the logarithmic curve
where
and b is given by
In our case
So we must find![\bf T_1](/tpl/images/0328/6893/a6a85.png)
We know that the cumulative average labor hours to assemble the first five units of product A was 15.962 hours, hence
applying the formula,
factorizing
computing the terms we have
Finally, to compute the time estimated to produce the 21st unit, we replace in the formula with n=21
