A company produces cholate bars. Assume 40-hour weeks and an hourly wage of $12. Overhead is 1.5 times weekly labor cost. Material cost is $6 per pound.

Week	Output (units)	Workers	Material (lbs)
1	30,000	6	450
2	33,600	7	470
3	32,200	7	460
4	35,400	8	480

1. Compute the multifactor productivity measure for Week 1 for production of chocolate bars.
2. Compute the multifactor productivity measure for Week 2 for production of chocolate bars.
3. Compute the multifactor productivity measure for Week 3 for production of chocolate bars.
4. Compute the multifactor productivity measure for Week 4 for production of chocolate bars.

Problem 2:

A manager checked production records and found that a worker produced 120 units while working 50 hours. In the previous week, the same worker produced 400 units while working 40 hours. Did the worker's productivity increase, decrease, or remain the same? Explain.
