Problem 4: A small firm intends to increase the capacity of a bottleneck operation by adding a new machine. Two alternatives, A and B have been identified, and the associated costs and revenues have been estimated. Annual fixed cost would be $40,000 for A and $30,000 for B; variable costs per unit would be $10 for A and $11 for B; and revenue per unit would be $15. a. Determine each alternative's break-even point in units. b. At what volume of output would the two alternatives would yield the higher profit? c. If expected annual demand is 12,000 units, which alternative would yield the higher profit
