I'd like to buy some meat.
What kind would you like today?
I'd like a pound of roast beef. That's my son's favorite sandwich meat.
Really? My daughter likes it, too. OK, that's going to be $5.50.
Perfect.
Anything else? Perhaps some pork?
No, but I do need 3 pounds of chicken breast. My husband wants it for the soup he likes to make.
That costs $4.00 a pound.
