I would like to get some meat today .   What kind do you need ?   I need about a pound of ground beef .   The ground beef is $ 2.48 a pound .   That sounds good .   What else would you like ?   I also need three pounds of chicken breasts .   The chicken breasts are $ 4.05 a pound .   How much will the three pounds of chicken cost altogether ?   Altogether , it's going to be $ 12.15 .   That will be all for me .
