Calculate the overall labor cost portion due to a task that

has a learning curve rate of $85\%$ and reaches steady state

value starting with the $17$ unit which $4\mathrm{.}90$ minutes per

unit.

Labor and benefits are $$25$ per hour, and the task

requires three skilled workers. Workers are paid a full

hourly rate for the fraction of hour when they work.

The overall production run is $23$ units.

a$)$ What is the steady$-$state time for the $17$th unit in

minutes$)?$

b$)$ What is the time to produce all $23$ units?

c$)$ What is the overall labor cost for all $23$ units $($round up

the time to the next integer$)?$
