Number of hamburgers sold= 700

Number of cheeseburgers sold= 900

Number of chicken sandwiches sold= 500

Total workforce= 5

In addition, it is also stated that one cheeseburger is equal to 1.25 hamburgers, and one chicken sandwich is equal to 0.80 hamburger.

Based on the given information,

Hamburgers = 700

1 Cheeseburger = 1.25 hamburgers

900 cheeseburgers = 720 hamburgers

1 Chicken sandwich = 0.8 hamburger

500 chicken sandwiches = $500÷0.8$= 625 hamburgers

Therefore, the total output $\begin{array}{l}=700+720+625\\ =2,045\end{array}$

Total workforce = 5

Total hours worked in a week = 40

Total input =$5×40=200$

$\begin{array}{c}\text{Productivity=}\frac{\text{Output}}{\text{Input}}\\ =\frac{2,045}{200}\\ =10.225\end{array}$

Based on the given information,

Hamburgers = 700

1 Cheeseburger= 1.25 hamburgers

700 cheeseburgers =$700÷1.25=560\text{hamburgers}$

1 Chicken sandwich= 0.8 hamburger

700 chicken sandwiches =$700÷0.8=875\text{hamburgers}$

Total output =$700+560+875=2,135$

For this scenario, the input is the same, which is 200

$\begin{array}{c}\text{Productivity=}\frac{\text{Output}}{\text{Input}}\\ =\frac{2,135}{200}\\ =10.675\end{array}$
