Remember the following comment from the chapter: "Anything you can do to accelerate the rate of learning will speed the cost savings." Let's put this to the test. Assume the following:

The supplier's learning rate is $30\%.$

So$,$ the process is operating on a $70\%$ learning curve.

Labor rates are still $$20$ per hour.

What would be the labor cost for the $250$ th unit?

$$198\mathrm{.}56$

$$234\mathrm{.}56$

$$132\mathrm{.}73$

$$173\mathrm{.}82$
