Tentukan nilai guna marginal

Nilai guna marginal / Marginal Utility (MU) adalah tambahan nilai guna yang diperoleh akibat penambahan penggunaan produk Rumus MU = ∆TU/∆Q Q = 0, TU = 0, MU = 0 Q = 1, TU = 40, MU = 40-0/1-0 = 40/1 = 40 Q = 2, TU = 70, MU = 70-40/2-1 = 30/1 = 30 Q = 3, TU = 90, MU = 90-70/3-2 = 20/1 = 20 Q = 4, TU = 100, MU = 100-90/4-3 = 10/1 = 10 Q = 5, TU = 100, MU = 100-100/5-4 = 0/1 = 0 Q = 6, TU = 90, MU = 90-100/6-5 = -10/1 = -10
