I need an answer for this quesion

A manager must decide which type of machine to buy. A. B. or C. Product forecasts and processing times on the machines are as follows: Assume that only purchasing costs are being considered. Which machine would have the lowest total cost, and how many of that machine would be needed? Machines operate 10 hours a day. 250 days a year. (Round up your answers to the next whole number. Omit the "$" sign in your response.) Consider this additional information: The machines differ in terms of hourly operating costs: The A machines have an hourly operating cost of $10 each. B machines have an hourly operating cost of $11 each, and C machines have an hourly operating cost of $12 each. Which machine would be selected, and how many of that machine would be needed, in order to minimize total cost while satisfying capacity processing requirements? (Do not round intermediate calculations and round your answers to the nearest whole number.)
