Central Manufacturing must implement a manufacturing process that reduces the amount of toxic by-products.  Two processes have been identified that provide the same level of toxic by-product reduction.  The first process would incur ${F1} of fixed costs and ${V1} per unit of variable costs.  The second process has fixed costs of {F2} and variable costs of ${V2} per unit. At what quantity does it not matter which of the two processes is chosen?
