Answer:
90 ATP
Explanation:
Every acetyl-CoA yields 3 NADH and 1 FADH2
18 carbon fatty acid is known to have 9 Acetyl CoA.
1 acetyl CoA produces a total of 10ATP.
Since the 18 carbon fatty acid has a total of 9 Acetyl CoA then the total number of ATP produced is 9* 10 which results in 90 ATP being formed when it passes through the various reaction mechanisms.
