conversations.value: It takes 15 mink skins to make a coat. Andy buys 30 minks and each mink has 6 babies, but half the total minks are set free by activists. How many coats can he make?
  Give me a detailed solution.
conversations.from: assistant
conversations.value: First find the total number of baby minks: 30 minks * 6 babies/mink = 180 minks
  Add this to the number of adult minks: 180 minks + 30 minks = 210 minks
  Then divide this number in half to find how many aren't set free: 210 minks / 2 = 105 minks
  Then divide the remaining number of minks by the number of minks per coat to find the number of coats: 105 minks / 15 minks/coat = 7 coats
