Process A has fixed costs of $2500 and variable costs of $10 per unit. Process B has fixed costs of $1000 and variable costs of $25 per unit. What is the crossover point for Process A and Process B? If we need to manufacture 75 units, which Process should we choose? a. Crossover = 200 units but we need 75 units so choose Process A b. Crossover = 200 units but we need 75 units so choose Process B c. Crossover 100 units but we need 75 units so choose Process A O d. Crossover 100 units but we need 75 units so choose Process B O e. Crossover is at fixed cost of $1500 for quantity of 75 units
