conversations.value: Solve the math problem: Gretchen's local ice cream shop offers 100 different flavors.  She was able to try a 1/4 of the flavors 2 years ago and double that amount last year.  How many more flavors will she need to try this year to have tried all 100 flavors?

conversations.value: The shop offers 100 flavors and she tried 1/4 of the flavors so she had 100*.25 = 25 flavors 2 years ago
  Last year she ate double the amount from the previous year so she had 25*2 = 50 flavors
  2 years ago she ate 25 flavors and last year she had 50 flavors so she has had 25+50 = 75 flavors
  The shop offers 100 flavors and she has had 75 flavors so she still needs to try 100-75 = 25 flavors
