$9.$ Given the following data, determine the total annual cost of making with each of process A and B and of buying. Estimated demand is $8,500$ units a year. The operations manager has said that it would be possible to achieve a $12$ percent reduction in the fixed cost of Process B and a $12$ percent reduction in B$$s variable cost per unit. Would that be enough to change your answer if the estimated annual cost to achieve those savings was $$5,000?$
