The formula to calculate the Air Consumption Cost (ACC) is:
\[ ACC = TAC \cdot CPUA \]
Where:
Let's say the total air consumed (TAC) is 100 tons, and the cost per unit of air (CPUA) is $50 per ton. Using the formula:
\[ ACC = 100 \cdot 50 = 5000 \, \text{\$} \]
So, the air consumption cost is $5000.
