conversations.value: Can you explain how to solve this math problem: A three-ounce box of flavored jello makes 10 small jello cups.  Greg wants to make small jello cups for his son's outdoor birthday party.  There will be 30 kids and he wants to have enough so that each kid can have 4 jello cups.  Jello is currently on sale for $1.25.  How much will he spend on jello?

conversations.value: There will be 30 kids and he wants each kid to have 4 servings so that's 30*4 = 120 jello cups
  1 box of jello makes 10 jello cups and he needs to make 120 jello cups so he needs 120/10 = 12 boxes of jello
  Each box of jello is $1.25 and he needs 12 boxes so he will spend 1.25*12 = $15.00 on jello
