Answer:
From the given question
For production of 1 unit of Laptop technicians require 21 Hours
Also given the learning curve is 78%
So ,to produce 8 units of laptops the time required by the technicians is
L=0.78
T1 =21 hrs
T8= T1 (N (log L/log 2)) = 21 (8 (log 0.78/log 2))
T8= 21 (8 (log 0.78/log 2))
