Aprendiz Co is a manufacturer of designer clothing and is creating a range of products which will incorporate recent developments in technology. Z-Tie Production is about to begin on a new fashion accessory called the Z-Tie. This is a wearable, interactive product which will work with customers' smartphones. The design and assembly of the Z-Tie is complex and much of the work is performed manually. Workers have already expressed concerns regarding the output targets they are required to meet. Management of Aprendiz Co have assured the workers that they will get faster at producing Z-Ties and explained that a learning rate of 95% was incorporated into the calculation of production targets. The first unit of Z-Tie took 25 hours to produce and the first customer order for 128 units has been received. Z-Hat This product has been in production for six months now. A 95\% learning rate was also assumed for the Z-Hat. Data for the Z-Hat shows that the first order of 150 units was completed in 725 hours. Z-Belt This product has now reached its steady state. Like the other products, an assumption was made that the learning rate would have been 95% for the first customer order. However, a review has shown that the actual learning rate which was achieved was 80%. Leerling Co Leerling C0 is a direct competitor to Aprendiz C0 and has begun production of a rival product to the Z-Tie, called the Copy-Tie. Leerling Co is hoping to benefit by releasing its Copy-Tie before the Z-Tie reaches the market. Information relating to production of the Copy-Tie' is given below: Assuming a 95% learning rate applies throughout, how long will it take in total to produce all 128 units of the Z-Tie (to the nearest hour)? 17 hours 70 hours 2,235 hours 4,582 hours
