A company that makes shopping carts for supermarkets and other stores recently purchased somenew equipment that reduces the labor content of the jobs needed to produce the shopping carts.Prior to buying the new equipment, the company used five workers, who produced an average of80 carts per hour. Workers receive $10 per hour, and machine cost was $40 per hour. With the newequipment, it was possible to transfer one of the workers to another department, and equipment costincreased by $10 per hour while output increased by four carts per hour.a. Compute labor productivity under each system. Use carts per worker per hour as the measure oflabor productivity.

A Company that makes shopping carts for supermarkets and other stores recently purchased some new equipment that reduces the labor content of the jobs needed to produce the shopping carts. Prior to buying the new equipment, the company used 6 workers, who produced an average of 78 carts per hour. Workers receive $10 per hour, and machine coast was $36 per hour. With the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by $13 per hour while output increased by four carts per hour.a) Compute the multifactor productivity (MFP) (labor plus equipment) under the Prior to buying the new equipment. The MFP (carts/$) = (round to 4 decimal places).b) Compute the % growth in productivity between the Prior to and after buying the new equipment. The growth in productivity = % (round to 2 decimal places)
A company that makes shopping carts for supermarkets and other stores recently purchased some new equipment that reduces the labor content of the jobs needed to produce the shopping carts. Prior to buying the new equipment, the company used 5 workers, who together produced an average of 90 carts per hour. Workers receive $13 per hour, and machine cost was $30 per hour. With the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by $10 per hour while output increased by 5 carts per hour. a.

In the welding operations of a bicycle manufacturer, a bike frame has a flow time of about 11.5 hours. The time in the welding operation is spent as follows: 2 hours waiting in front of the cutting machine for the batch to start, 2 hours waiting for the setup of the machine, 1 hour waiting for the other pieces of the batch to go through cutting, 1 minute at the cutting machine, and 3 hours waiting for the transfer to the welding machine. Then, at the welding machine, the unit spends 1 hour waiting in front of the welding machine for the batch to start, 1 hour waiting for the setup of the welding machine, 0.5 hour waiting for the other pieces of the batch to go through welding, 0.5 minute at the welding machine, and 1 hour waiting for the transfer to the next department. Determine the exact flow time. What is the value-added percentage of the flow time?(round percentage answer to 4 decimal places.) answer:_______percent

A company that makes shopping carts for supermarkets and other stores recently purchased some new equipment that reduces the labour content of the jobs needed to produce the shopping carts. Prior to buying the new equipment, the company used five workers, who produced an average of 100 carts per hour. Workers receive $10 per hour, and machine cost was $40 per hour. With the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by $10 per hour while output increased by 20 carts per hour. a. The labor productivity under the old system is Blank 1. Fill in the blank, read surrounding text. and the new system is Blank 2.

A Company that makes shopping carts for supermarkets and other stores recently purchased some new equipment that reduces the labor content of the jobs needed to produce the shopping carts. Prior to buying the new equipment, the company used 4 workers, who produced an average of 87 carts per hour. Workers receive $13 per hour, and machine coast was $32 per hour. With the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by $18 per hour while output increased by four carts per hour. a) Compute the multifactor productivity (MFP) (labor plus equipment) under the Prior to buying the new equipment. The MFP (carts/$) = .6949 (round to 4 decimal places). b) Compute the % growth in productivity between the Prior to and after buying the new equipment. The growth in productivity = 25.55 % (round to 2 decimal places)

Charles Lackey operates a bakery in Idaho Falls, Idaho. Because of its excellent product and excellent location, demand has increased by 55% in the last year. On far too many occasions, customers have not been able to purchase the bread of their choice. Because of the size of the store, no new ovens can be added. At a staff meeting, one employee suggested ways to load the ovens differently so that more loaves of bread can be baked at one time. This new process will require that the ovens be loaded by hand, requiring additional manpower. This is the only thing to be changed. The bakery currently makes 1,800 loaves per month. The pay will be $8 per hour for employees and each employee works 160 hours per month. Charles Lackey can also improve the yield by purchasing a new blender. The new blender will mean an increase in his investment. This new blender will mean an increase in his costs of $125 per month, but he will achieve the same new output (an increase to 2,790.00) as the…

Cubway, the sandwich shop, is run by Jim, Tim and Kim. When a customer arrives, Jim spends 5 minutes taking order from the customer. After this, Tim prepares bread and Kim prepares filling for the order. These activities are performed in parallel, and take 6 and 12 minutes respectively. Jim then assembles the bread and filling, which takes 4 minutes of his time. Finally, Tim spends 1 minutes in delivering the order and taking payment. What is maximum number of sandwiches Cubway can make per hour? (In other words, what is the capacity of the process in sandwiches per hour?)
