Answer:
Total revenue= -$60
Step-by-step explanation:
First, we need to determine the total cost of producing 400 loaves:
Total cost= 6*40 + 8*60 + 2*60 + 1*20
Total cost= $860
Now, we can calculate the total revenue:
Total revenue= total income - total cost
Total revenue= 400*2 - 860
Total revenue= -$60
