Một xí nghiệp tư nhân sản xuất 2.000 sản phẩm/1 ngày (8 tiếng). Họ phải đầu tư ban đầu là 800.000 USD. Trong đó chi phỉ Máy móc, thiết bị, nhà xưởng là 500.000 USD, nguyên nhiên vật liệu chiếm 1/5 giá trị máy móc thiết bị nhà xưởng. Biết rằng tỷ suất giá trị thặng dư là 300%. Hãy xác định Giá trị mới trong một đơn vị sản phẩm là bao nhiêu? b. Cấu tạo hữu cơ của tư bản là bao nhiêu? a. Nếu cung bằng cầu, giá cả của một đơn vị hàng hóa là bao nhiêu. d. Nếu năng suất lao động tăng 100%, các yếu tố khác không đổi, giá cả một đơn vị hàng hóa là bao nhiều
