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? Let's be accurate as possible.
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.
The answer: 159.
