Question

Quizplus · Accepted Answer

The 80% learning curve implies that each subsequent unit takes 80% of the time of the previous unit. If the first product took X hours, the second took 0.8X hours. Together, they took X + 0.8X = 1.8X hours. Given 1.8X = 18 hours, X = 10 hours for the first product, so the second product took 0.8 * 10 = 8 hours.
