A company is developing @linear programming model for a hybrid aggregate plan that combines pure chase demand with level production strategies.. Each worker can produce 500 units per period. The production constraint for period 3 is A. number of workers in period 3 / 500 = units produced in period 3 B. 500 (number of workers in period 2 + number of workers hired in period 3) = units produced in period 3 C. 500 number of workers hired in period 3 + inventory in period 3 = demand in period 3 D.500 x number of workers in period 3 = units produced in period 3
