conversations.value: I'm stuck on this math problem: Mr. Smith takes his wife, his parents, and his 3 children to a seafood buffet.  The price for the adult buffet is $30.  The price for the children’s buffet is $15.  Senior citizens get a 10% discount.  How much does Mr. Smith spend on the buffet for his entire family?
  Can you help?

conversations.value: The buffet cost for Mr. Smith and his wife is $30 x 2 = $60.
  The buffet cost for his children is $15 x 3 = $45.
  The buffet cost for 1 senior citizen is $30 x 90% = $27.
  B
  uffet cost for the grandparents is $27 x 2 = $54.
  Buffet cost for the entire family is $60 + $45 + $54 = $159
