|||
| Direct materials | $ | 6.70 | |
| Direct labor | $ | 4.20 | |
| Variable manufacturing overhead | $ | 1.40 | |
| Fixed manufacturing overhead | $ | 4.70 | |
| Fixed selling expense | $ | 3.70 | |
| Fixed administrative expense | $ | 2.10 | |
| Sales commissions | $ | 1.10 | |
| Variable administrative expense | $ | 0.55 | |
| 14-a. | 
 If 12,400 units are produced, what are the total amount of direct manufacturing costs incurred to support this level of production  | 
| 14-b. | 
 If 12,400 units are produced, what are the total amount of indirect manufacturing costs incurred to support this level of production?  | 
| 15. | 
 What total incremental cost will Martinez incur if it increases production from 11,400 to 11,401 units? (Round your answer to 2 decimal places.)  | 
         
    
| On production of 11400units | On production of 12400units | ||
| Particulars | Amount per unit in $ | Amount per unit in $ | |
| Direct Materials | 6.7 | 6.7/11400*12400= $ 7.29 | |
| Direct Labour | 4.2 | 4.2/11400*12400= $4.57 | |
| Variable Manufacturing Overhead | 1.4 | 1.4/11400*12400= $1.52 | |
| Fixed Manufacturing Overhead | 4.7 | ||
| Fixed Selling expense | 3.7 | ||
| Fixed administrative expense | 2.1 | ||
| Sales commissions | 1.1 | ||
| Variable Administrative expense | 0.55 | ||
| 14. a) | If 12,400 units are produced, the total amount of direct manufacturing costs incurred to support this level of production will be | ||
| (Direct Material + Direct Labour) * No. of units | |||
| ($7.29 +$4.57 ) *12400 | $147064 | ||
| 14. b) | If 12,400 units are produced, the total amount of indirect manufacturing costs incurred to support this level of production will be | ||
| Fixed Manufacturing Overhead + (Variable Manufacturing Overhead* No. of units) | |||
| $4.7*11400 +$1.52*12400 | $72428 | ||
| 15 | Total incremental cost which Martinez will incur if it increases production from 11,400 to 11,401 units will be | ||
| Only manufacturing cost that are variable will be incurred additional cost as rest are either fixed or sales & administrative costs. | |||
| (Direct Material+ Direct Labour+ Variable Manufacturing Overhead) | |||
| $6.7+$4.2+$ 1.4 | $12.3 will be the incremental cost | ||
