Revenue from each product in January = Units Produced in Jan * Cost per Unit in Jan. Product A: 15,000 * 120 = 1,800,000 Product B: 25,000 * 150 = 3,750,000 Product C: 10,000 * 200 = 2,000,000 Product D: 22,000 * 110 = 2,420,000 Product E: 28,000 * 90 = 2,520,000 Total revenue in January = 1,800,000 + 3,750,000 + 2,000,000 + 2,420,000 + 2,520,000 = 12,490,000. Answer: d) 12,490,000
