Answer:
b. this producer is losing $2,000 a week.
Explanation:
The computation is shown below:
As we know that
Profit = (Price - Average total cost) × Quantity
= ($500 - $600) × 20
= -$2,000
This negative amount represents that there is a loss of -$2,000
Hence, option B is correct as the producer losing $2,000 in a week
Therefore all the other options are wrong
