Answer: $35
Step-by-step explanation:
Profit will be the Total Revenue less the total costs involved with selling the goods.
Total Revenue at $16 is $640.
Total Cost at $16 is $605.
Profit = 640 - 605
= $35
Note; Your question has $15 as the maximizing price which is not available in the table. It might be a typo so I attached the question.
