A manager must decide which type of machine to buy. A, B, C C Machine costs (per ndividual machine) are as follows Product forecasts and processing times on the machines are as follows: Click here for the Excel Data File a. Assume that only purchasing costs are being considered. Compuse the total processing time required for each machine type to meet demand, how many of each machine type would be needed, and the resulting total purchasing cost for each machine type. The machines will operate 10 houss a dyy, 240 days a yeac, (Enter total prosessing times as whole numbers. Round up machine gusmtities to the next higher whole numbet Compute total purchasing costs using these rounded machine euransties. Enter the resulting total purchasing cost as a whole number.? b. Consider this additional intormation The machines drfer in terms of houty operating costs: The A machines have an hourly operating cost of $13 each, 8 machines have an houny operating cost of $15 each, and C machines have an hourly operasing cost of $10 each. What would be the total cost associated with each machine option, including both the initial purchasing cost and the annual operating cost inciared to satisfy demand? Use rounded machine quantities from Part a. Do not round any other intermediate calculations. Round your final answers to the nearest whole number.)
