1. A firm is paying $15,000 in rent monthly, and the cost of transportation, raw materials, and labor is $130 per piece. If a single unit is sold for $550. A) If the firm sells 8500 units monthly, determine the total cost, total revenue, and profit. B) Determine the Break-even volume.

In the next period, the monthly sale is increased by 700 units and also the cost of transportation, raw materials, and labor by $50 per piece. Determine the total cost, total revenue, and profit. Also, determine the Break-even volume. Explain the Management Science approach to problem-solving with a suitable figure.
