yes that makes it more clear i appreciate your help i have a IV med math test tomorrow

There is not *a* formula to solve this problem. You have to think about what's being asked. The only think you have to think about is what you started with, how much went in, and how much is left when you have to recalculate.

This is the problem with formulae. So often I see students try to cram every possible bit of data in the question into an equation...and a lot of it is not needed for the answer. Does make for a lot of unnecessary confusion.

We see people here all the time that can't read a problem, see which data points are needed and which are distractors/extraneous, and they cram all of it into a big dimensional analysis thing, or some other "sure-fire formula," and come up with a nonsensical answer, and then get flustered and confused. The people who write exams know this, and so they give distractors (wrong answers) that will result when numbers are slotted into formulae without understanding, knowing that some people will pick them because they have no idea to think about the problem. So I prefer to get people to back away, slowly, from the formulae and think about what is going on, what's really being asked, and look at what they know before they start getting flustered about OMGIHAVETOSOLVEAPROBLEM!!!!! :)

Here's another really good thread to help you take that step back and think before you act. As our beloved Swami Beyondananda says, "Don't just do something! Sit there!"
