If It = units in inventory at the end of period t, Pt = units produced in period t, and Dt = demand in period t, then the company’s demand constraint to ensure that demand is met in quarter 3 is (1 Point) = a. D3 = 12-13 + P3 O b. D3 = 13 + P3 O c. D3 = 13 – 12 + P3 c d. D3 = 12 – 13 + P2 14 What is this system’s reliability?
