Answer:
Myanmar = $0.39
Explanation:
In this question, we find the labor cost per unit for each :
Labor cost per unit = (Number of labors Ă— Wage rate per day) Ă· (number of units produced)
For Myanmar:
Labor cost per unit would be:
= (6 labors Ă— $2.5) Ă· (38 units)
= $15 Ă· 38 units
= $0.39
For China:
Labor cost per unit would be:
= (11 labors Ă— $1.75) Ă· (48 units)
= $19.25 Ă· 48 units
= $0.40
For Montana:
Labor cost per unit would be:
= (3 labors Ă— $60) Ă· (105 units)
= $180 Ă· 105 units
= $1.71
So, the most economical would be  Myanmar as it has the least labor cost per unit among these two.
