conversations.value: Bob enters cycling competitions every single week and hopes to win the 100 dollar grand prize each time. For the first 2 weeks, he managed first place and got 100 dollars each week. He is saving up for a puppy that costs 1000 dollars. What is the minimum number of additional weeks Bob must win first place?

conversations.value: Two weeks already passed and Bob has 200 dollars.
  Bob needs 1000-200=800 more dollars.
  Bob needs to win the competition for at least 800/100=8 more weeks.
