I want to buy some meat .   What kind would you like ?   I want one pound of ground beef .   That's going to be about $ 2.48 .   That will be fine .   What else can I get for you ?   Let me also have three pounds of chicken breasts .   That's going to be $ 4.05 a pound .   Can you tell me the total cost of the chicken breasts ?   That will be $ 12.15 .   That's all I'm going to get today .
