Suppose the first aircraft took 100 hours. If the improvement rate changes to 20%, how will the total time to complete both aircraft change? A) no change B) -10 hours C) + 10 hours D) -50 hours E) + 50 hours 19) Suppose that there are two products with the same first product time. However, product A has an improvement rate of 10% while product B has an improvement rate of 20%. How much longer will it take to make the 10th unit of product A compared to product B? A) Both will have the identical time for the 10th unit. B) A will take 48% more time. C) A will take 48% less time. D) A will take 23% less time. E) none of the above 20) The first unit of a product took 832 hours to build, and the learning curve is 90%. How long will it take to make the 25th unit?
