conversations.value: Can you give me some step-by-step instructions for this math problem: Marie has 4 notebooks with 20 stamps each. She also has two binders with 50 stamps each. If she decides to only keep 1/4 of the stamps, how many stamps can she give away?
conversations.from: assistant
conversations.value: Marie has 4 x 20 = 80 stamps from her notebooks.
  And she has 2 x 50 = 100 stamps from her binders.
  So she has a total of 80 + 100 = 180 stamps.
  Marie decided to keep 180 x 1/4 = 45 stamps only.
  Therefore, she can give away 180 - 45 = 135 stamps.
