According to theory, the time per unit decreases at a constant rate each time the output doubles
(e.g., unit 1 to 2, 2 to 4, and 3 to 6). The ratios of these observed times will give us an approximate
rate.
Unit 2/Unit 1 = 710/860 = 83%
Unit 4/Unit 2 = 600/710 = 85%
Unit 6/Unit 3 = 560/660 = 85%
a) Learning rate = 85%
b) Time to make 200 units = Time for 1st unit*Total time factor for 200 units at 85% Learning curve = 860*74.79 = 64,319.4
Time for 1st 10 units = 860+710+660+600+590+560+540+530+510+500 = 6060
Time for next 190 units = 64319.4 - 6060 = 58259 hours
c) Time for 1000th unit = Time for 1st unit*Unit time factor for 1000th unit at 85% learning curve = 860*0.1980 = 170 hours
