conversations.value: Maddie went to a beauty store and bought some beauty products. She bought 3 different makeup palettes which cost $15 each, 4 lipsticks which cost $2.50, and 3 boxes of hair color which cost $4 each. How much did Maddie pay in total?
  How to solve this?
conversations.from: assistant
conversations.value: She paid 3 x $15 = $45 for the makeup palettes.
  She paid 4 x $2.50 = $10 for the lipsticks.
  She also paid 3 x $4 = $12 for the boxes of hair color.
  Therefore, Maddie paid a total of $45 + $10 + $12 = $67 for the beauty products.
