Hello and good day:

I'm a homeschool mom and need a bit of help. I am not a math wiz and wish I were. I have some difficulty remembering how to do some things in math and could use assistance. Its always fun to see how it should have been done compared to what I did. Anyway, I am assisting my daughters and the math wiz is now in college. Could you help me remember how to set up this word problem?

To make an A the student needs a 94 and has averaged 91 on the first three tests. What does the student need to average on the last three tests to achieve the 94 for an A?
