A Highway contractor has four locations A, B, C, and D on a road contract which crushed stone is to be delivered. The stone, which is all of the same quality is to be supplied from three quarries 1, 2, and 3. The table below shows the relative transportation cost per cubic meter of transporting stone from each quarry to each site. However, the contractor discovered a technical problem in the third quarry, which results in a temporary shutdown of the facility. Based on this new condition, the contractor must deliver the crushed stone from the first and the second quarries only. Any shortage in the required crushed stone has to be covered from an external source. a) What is the optimal allocation of the crushed stone from each quarry to each location under the new circumstances? b) What is the transportation cost corresponding to the solution obtained in part a? c) Which of the four sites are affected by the shortage that results from the shutdown of the third quarry?
On January 1, 1978, the purchasing engineer of a Cement Co. purchased a new machine at a cost of140,000. Depreciation has been computed by the straight-line method based on an estimated useful lifeof five years and residual scrap value of 12,800. On January 2, 1981, extraordinary repairs (which werealmost equivalent to a rebuilding of machinery) were performed at a cost of 30,400. Because of thethorough going nature of these repairs, the normal life of the machinery was extended materially. Therevised estimate of useful life was four years from January 1, 1981.Determine the annual provision for depreciation for the years 1978 to 1980 and the adjusted provisionfor depreciation on December 31, 1981. Assume payment in cash for the machine and extraordinaryrepairs. construct a straight line method
