Answer: 1 widget per dollar
Explanation:
The weekly productivity level for this operation will be calculated thus:
Output = 8000 widgets per week.
Input = Labor Cost + Material Cost
= (5 × 40 × $15) + (100 × $50)
= $3000 + $5000
= $8000
Productivity = Output / Input
= $8000 / $8000
= 1 widget per dollar
