A. Period 1:32 units: Period 2:0 units; Period 3:0 units; Period 4:39 units B. Period 1 : 21 units; Period 2: 4 units; Period 3:17 units; Period 4:29 units C. Period 1 : 42 units; Period 2:0 units; Period 3:0 units; Period 4 : 29 units D. Period 1 : 15 units; Period 2:0 units; Period 3:56 units; Period 4:0 units E. Period 1:11 units; Period 2: 21 units, Period 3:0 units; Period 4:39 units 7-suppose that 10 additional units are needed in period 4. What are total costs for each period by using Wagner Within method? A. Period 1 : $11; Period 2:$ 83.95; Period 3: $0; Period 4 : $213 B. Period 1 :$ 11; Period 2: $ 16; Period 3 : $279.25 ; Period 4 : $0 C. Period 1: $11; Period 2: $ 16; Period 3 : $106; Period 4:$ D. Period 1 : $ 102.25; Period 2:$ 0; Period 3: $0; Period 4: $213 E. Period 1: $16.2; Period 2: $ 0; Period 3 : $299.75; Period 4: $0
