A hamburger factory produces 8,500 hamburgers each week. Assume there are 50 working weeks per year. The equipment used for making hamburgers costs $50,000 and will remain productive for 5 years. The factory has 10 employees and the average monthly salary is $4,000 per person. The average utility cost for the factory is $5,000 per month.

Note:
***Final answers as bold italic
What is the factory's hamburger output per year?
8500 per week and 50 weeks a year
= 8500*50 = 425000
What is the factory's labor cost per year?
Average monthly salary is $4000 per person
Per person annual salary = 4000*12 = $48000
Number of workers = 10
Hence total salary = 480000
What is the factory's equipment cost per year?
Equipment costs $50,000
Useful life = 5 years
Hence cost per year = 10000
What is the factory's labor productivity (hamburger/$)?
Per year labor cost = $480000
Per year hamburger produced = 425000
Hence labor productivity = total hamburgers/total labor cost = 425000/480000 = 0.88 hamburgers per $
What is the factory's multi-factor productivity, in terms of equipment and utility?
Per year equipment cost = $10000
Per year utility = 5000*12 = $60,000
Total cost = $70,000
Total output = 425000
Hence productivity = 425000/70000 = 6.07 hamburgers per $
What is the factory's total productivity?
Total cost = equipment + utility + labor = 480000 + 70000 = 550000
Output = 425000 hamburgers
Productivity = 425000/550000 = 0.77 hamburgers per dollar
Question – 2:
What is the labor cost per day for the seafood company?
Per day 3 shifts of 6 hours = 18 hours work
4 workers in each shift. Means 18*4 working labor hours = 72 labor hours
$10 per hour
Hence per day labor cost = $720
What is utility cost per day for the seafood company?
Utility cost per hour = $30
Per day working hours = 18
Hence total utility cost per day = 18*30 = $540
What is the utility productivity for the seafood company?
Daily utility cost = $540
Daily production = 550 boxes
Hence productivity = 550/540 = 1.01 boxes per dollar
What is the total productivity for the seafood company?
Per day total cost = total labor + utility = 540 + 720 = 1260
Total output = 550 boxes
Productivity = 550/1260 = 0.43 boxes per dollar
