Answer:
Incremental cost of buying = $2.50
Step-by-step explanation:
Cost per unit;
Direct materials = $10.30
Direct labor = $24.30
Overhead = $16.30
Total Overhead cost = 10.30 + 24.30 + 16.30
                                   = $50.90
Where the item is purchased,
Total cost = $46.88 + (40% × 16.30)
                 = $46.88 + $6.52
                 = $53.40
Cost difference = $53.40 - $50.90
                           = $2.50
There is an incremental cost of buying. This amounts to $2.50
 
        
             
        
        
        
Step-by-step explanation:
12a = 2×2×3×a
16 c^2 = 2×2×2×2×c×c
hence h.c.f = 2×2
 = 4
