The Emerson Corporation, a manufacturer of airplane landing gear equipment, is trying to develop a learning curve model to help forecast labor costs for successive units of one of its products. From past data, the firm knows that labor costs of the 25th, 75th, and 125th units were $800, $600, and $500, respectively. Using the learning curve equation for these labor costs, log C = 3.30755 − 0.28724 log Q, calculate the estimated cost of the 200th unit of output. What is the percentage of learning at Emerson?
