problem_description: Statement
  
  In "Takahashi-ya", a ramen restaurant, a bowl of ramen costs 700 yen (the
  currency of Japan), plus 100 yen for each kind of topping (boiled egg, sliced
  pork, green onions).
  
  A customer ordered a bowl of ramen and told which toppings to put on his ramen
  to a clerk. The clerk took a memo of the order as a string S. S is three
  characters long, and if the first character in S is `o`, it means the ramen
  should be topped with boiled egg; if that character is `x`, it means the ramen
  should not be topped with boiled egg. Similarly, the second and third
  characters in S mean the presence or absence of sliced pork and green onions
  on top of the ramen.
  
  Write a program that, when S is given, prints the price of the corresponding
  bowl of ramen.
