conversations.value: Can you guide me through solving this problem: At a birthday party, 30% of the guests are married, 50% are single, and the rest are children. If there are 1000 guests, how many more married people are there than children?

conversations.value: There are 1000 x 30/100 = 300 people who are married.
  There are 1000 x 50/100 = 500 people who are single.
  So, there are a total of 300 + 500 = 800 that are either married or single.
  This means, 1000 - 800 = 200 are children.
  Therefore, there are 300 - 200 = 100 more married people than children.
