1. A 2-man crew made 180 widgets in 10 hours, while a 3-man crew made 120 widgets in 4 hours, and a 5-man crew made 110 widgets in 2 hours. What is each crew's productivity as measured by widgets per man-hour? Which crew is the most productive?

2. A company that processes fruits and vegetables is able to produce 400 cases of canned peaches in one half hour with four workers. What is the labor productivity?

3. Kleen Karpets cleaned 5000 square feet of rugs last month, consuming 400 hours of labor at $10 per hour, 100 gallons of solvent at $5 per gallon, and 20 days of machine rental at $25 per day. What is the multifactor productivity for the month as measured by square feet of rugs per dollar spent?

4. A wrapping paper company produced 2,000 rolls of paper one day. Standard price is $0.75/roll. Labor cost was $ 160, material cost was $ 50, and overhead was $ 320. Determine the multifactor productivity in terms of dollars of output per dollars of input.

5. Collins Little Company has a staff of 4 employees, each working 8 hours per day at a rate of $20/hour. Their overhead expenses are $200/day. Collins processes and closes on 12 titles each day. They are considering purchasing a computerized title search system that will allow the processing of 20 titles per day. With the new system, they could cut their staff to 2 employees working the same hours at the same pay, but their overhead expenses would double to $400 per day.
