conversations.value: I need help with this problem:
  Scott, Mary, and Ken committed to raising $4,000 for their local children’s cancer hospital. Right now, Mary’s collection is five times what Ken has, but three times Scott’s funds. If Ken has $600, by how much have the three exceeded their goal?

conversations.value: Mary has collected 5 * $600 = $3000
  Scott therefore has $3000 / 3 = $1000
  All together, they have raised $3000 + $1000 + $600 = $4600
  They have therefore exceeded their goal by $4600 - $4000 = $600
