Product forecasts and processing times on the machines are as follows: a. Assume that only purchasing costs are being considered. Compute 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 hours a day, 210 days a year. (Enter total processing times as whole numbers. Round up machine quantities to the next higher whole number. Compute total purchasing costs using these rounded machine quantities. Enter the resulting total purchasing cost as a whole number.) b. Consider this additional information: The machines differ in terms of hourly operating costs: The A machines have an hourly operating cost of $13 each, B machines have an hourly operating cost of $15 each, and C machines have an hourly operating cost of operating cost incurred 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.) A firm plans to begin production of a new small appliance. The manager must decide whether to purchase the motors for the appliance from a vendor at $8 each or to produce them in-house. Either of two processes could be used for in-house production; Process A would have an annual fixed cost of $175,000 and a variable cost of $7 per unit, and Process B would have an annual fixed cost of $195,000 and a variable cost of $6 per unit. Determine the range of annual volume for which each of the alternatives would be best. (Round your first answer to the nearest whole number. Include the indifference value itself in this answer.)
