Answer:
The average product for the 10 workers is 350 sandwiches per month.
Step-by-step explanation:
Average product is given by total output divided by total labor used
Total output per month = 3500 sandwiches
Total labor used per month = 10 workers
Average product = 3500 ÷ 10 = 350
Average product for the 10 workers is 350 sandwiches/month
