Answer: $0.1
Explanation:
Per unit cost of production = Total cost of factors of production / total quantity
Total cost of Labour = $3 × 8 = $24
Total cost of capital = $10 × 2 = $20
Total cost of raw materials = $4 × 5 = $20
Total cost of factors of production = $24 +$20 + $20 = $64
$64 / 640 = $0.1
