3 bottles sounds way too low for this concentration.

I feel like I should be able to figure this out, but I can't remember if we need to convert everything to the same units first. What if I miscalculate the total volume?

If I recall correctly, we need to find the difference between the strengths and then calculate how much of each solution we need. I hope I remember the right formula!

I think we practiced a similar question in class where we had to mix different strengths. I might need to double-check the calculations for the volumes.

I remember something about using alligation to find the amounts needed, but I'm not sure how to set it up for this specific problem.

Ugh, I hate questions about inventory management. There are so many factors to consider. I'll have to really think through the potential negatives here.

I think the answer is A, but I'm not 100% certain. I'll make a note to double-check the details of the amendment to Section 43A before submitting my final answer.

I remember we discussed thermal fatigue in class, but I'm not entirely sure if that's the main issue here with condensate in the steam.
