why did you do 300 instead of 1200 and instead of 6 you took 3?
1) Red Point Alloys BV produces cast bronze valves for use in offshore oil platforms. Currently, Red Point produces 1600 valves per day. The 20 workers at Red Point work from 7 a.m. until 7 p.m., with 30 minutes off for lunch and a 15-minute break during the morning work session and another at the afternoon work session Red Point is in a competitive industry and needs to increase productivity to stay competitive. They feel that a 20 percent increase is needed.
Red Point’s management believes that the 20 percent increase will not be possible without a change in working conditions, so they change work hours. The new schedule calls on workers to work from 7:30 a.m. until 7:30 p.m., during which workers can take one hour off at any time of their choosing. Obviously, the number of paid hours is the same as before, but production increases, perhaps because workers are given a bit more control over their workday. After this change, valve production increased to 1800 units per day.

- the final answer is 0.5 A production machine operates in a semi-automatic cycle but a worker must attend the machine 100% of the time to load parts. Unloading is accomplished automatically. The worker's cost rate = 37$/hr including applicable labor overhead rate. To produce the parts, the production machine was bought six years ago for installed price of $750,000. At that time it was anticipated that the machine would last 8 years and be used 5000 hours per year. However, it is now in need of major repairs that will cost $166,500. These repairs will be made and as a result, the machine will last three years, operating 4000 hours per year. Applicable overhead rate for the machine = 42%. Cost of the starting parts = 0.12$/pc. The job runs several months so the effect of setup can be ignored. Each cycle, the actual process time = 26s, and time to load the part = 18 s. Automatic unloading takes 4 s. A proposal has been made to install an automatic parts-loading device on the machine.

What is the machine cost/ hr which must be charged in order to amortise the costs over the 6 year period? Express your answer in £/ hour but just write the numerical answer rounded up to the nearest penny. To make the calculation simpler ignore the effects of compound interest, you can assume that over the 6 year period you will be required to pay back borrowed money for the machine purchase amounting to 6% interest on the sum borrowed.arrow_forward
