Need Urgent Help on math problem: Margaret painted a mural for St. Patrick’s Day...

question 1:

Margaret painted a mural for St. Patrick’s Day and mixed her own green paint. She mixed 3 parts yellow paint with 2 parts blue paint to create green paint. Maureen wanted to also paint a mural with the same green color, but she currently has 8 cups of green paint that is a mixture of 40% yellow paint and 60% blue paint. To get the same shade of green as Margaret, how many cups of yellow paint must she add to her mixture?

question 2;

Let’s now take a look at the word GREEN. There’s not too many real words that can be made from the letters in GREEN. For this problem, though, let’s see how many ways we can arrange the five letters in the word GREEN, even if they don’t form real words. But let’s also add a restriction: any arrangement must keep the two Es together. How many such arrangements are there?

To learn how to set up and solve "mixture" type exercises, please try here. Once you have studied the lesson and learned the basic terms and techniques, please attempt the exercise.

You've been given, in effect, four "things" (being EE, G, N, and R), and have been asked to figure out the number of ways that you can line them up. What formula did they give you for this? Plug into that, and see what you get.

If you get stuck, please reply with a clear listing of your thoughts and efforts so far, so we can see where things are going sideways. Thank you!
