Please help! These problems confuse me so much, and I won't have access to help at school until the weekend. I don't have a lot of experience in mixture problems and the examples in my notes don't follow the structure of this particular problem.
I have tried to make charts but I can't seem to make one that works with this problem. My charts have listed: the percent solution, the total liters, and I don't know what else to include. I don't think I was filling the chart out right.
Feel free to change the numbers in the problem to answer it, but PLEASE follow the same structure, that is what is confusing me most!
Thank you!
