Variable Costs for one unit = $ 5.30 + $ 2.80 + $ 1.40 + $ 1.20 + $ 0.45 = $ 11.15
6. 12,500 units x $ 11.15 = $ 139,375
7. Fixed Manufacturing Overhead = $ 4.00 / unit
( $ 4.00 x 10,000 units ) / 8,000 units = $ 5 / unit
8. Fixed Manufacturing Overhead = $ 4.00 / unit
( $ 4.00 x 10,000 units ) / 12,500 units = $ 3.2 / unit
10. 12,500 x $ 3.2 = $ 40,000
6: $139,375
7: $5.00/unit
8: $3.2/unit
