messages.content: First find the total number of items in the attic by dividing the number of useful items by the percentage of useful items: 8 items / .2 = <<8/.2=40>>40 items
  Then multiply the total number of items by the percentage that are junk to find the number of junk items: 40 items * .7 = <<40*.7=28>>28 items
