A tailor must make 7 of the same size suits for a client. The first suit took 13.9 hours to make and the last suit took 7.3 hours to make. What was the tailor\'s learning curve % of this run of suits assuming a steady state of production is never reached? Express your answer in % to the nearest 0.1%

Solution

Using that linear growth was there in tailors learning
assuming he takes x times less hours less than previous suit
So for 7 suits he takes 13.9,13.9*x,13.9x^2 ... so on
for last suit 13.9x^6=7.3

x= 0.89
