B) Milk and dinner rolls are often served during the same meal.
C) Milk is one of the major ingredients used to make dinner rolls.

If x is fish, y is octopi, and z is crabs, then you would have to know the numbers. Then your answer would be c. 30x+80y-15z. Because x=+30, y=+80, and z=-15. I hope that helps. If you need any further help on this problem just ask.
