A fast-food restaurant serves hamburgers, cheeseburgers, and chicken sandwiches. The restaurant counts a cheeseburger as equivalent to 1.25 hamburgers and chicken sandwiches as 0.8 hamburger. Output is measured in the number of units produced. Current employment is five full-time employees (each working a 40-hour week).
1) In week one, if the restaurant sold 700 hamburgers, 900 cheeseburgers, and 500 chicken sandwiches in one week, what is its labor productivity?
2) Suppose you want to increase the productivity you just calculated by 10%. To do this, you can only increase the number of hamburgers while keeping the number of cheeseburgers, chicken sandwiches, conversion rates and labor hours the same. How many hamburgers would you need to make to achieve this goal? Leave the units in decimal form as follows x.xx.
3) In week two, what would its productivity have been if it had sold the same number of sandwiches (2,100) but the mix was 700 of each type?
4) What would be the percentage change in productivity from week one to week two?
